FORMATS



CONCEPT format is called the sheet of paper on which a drawing is made, the form and dimensions in mm. are normalized. In 1026-2 UNE 83 Part 2, equivalent to ISO 5457, specifies the characteristics of the formats.
DIMENSIONS The dimensions of the formats comply with the rules of folding, likeness and reference. According to which:
1 - A format is obtained by transverse bending of the immediate superior.
2 - The relationship between the sides of a format is equal to the ratio between the side of a square and diagonal, ie 1 /.
3 - And finally to obtain the formats form part of a basis of 1 m2.
Applying these three rules, determines the size of the A0 format called base whose dimensions would be 1189 x 841 mm.
The other formats of the series A, are obtained by successive folded A0 format.
The stable standard envelopes, folders, files, etc. two auxiliary series B and C.
Las dimensiones de los formatos de la serie B, se obtienen como media geométrica de los lados homólogos de dos formatos sucesivos de la serie A.
Los de la serie C, se obtienen como media geométricas de los lados homólogos de los correspondientes de la serie A y B.
Serie A Serie B Serie C
A0 841*1189 B0 1000*1414 C0 917*1297

FOLDING UNE - 1027 - 95, sets out how to fold the planes. This will zig-zag, both vertically and horizontally, until it was reduced to the dimensions of archiving. Also shown in this statement that the title block should always be on the front and visible.

on the Media menu
MARGINS: The formats should be drawn inside a box that delimits the area of \u200b\u200bdrawing useful. This box lets margins in the format that the rule provides that not less than 20 mm. for A0 and A1 formats, and not less than 10 mm. for A2, A3 and A4. If folding is expected to file with holes in the paper, you must define a range of archiving a minimum width of 20 mm., On the opposite side to the title block.
TABLE OF SIGNAGE: Also known as box, place den of the drawing area, and at the bottom right address being read, the same as the drawing. UNE - 1035 - 95, establishing the provision can take the picture with his two areas: the identification, maximum width 170 mm. and supplementary information, to be placed above or to the left of that.
CENTER SIGNS: Signs centered. They are placed strokes at the ends of the axis of symmetry of the format, in both directions. Minimum thickness of 0.5 mm. and surpassing the box in 5 mm. There must be a position tolerance of 0.5 mm. These marks are used to facilitate the reproduction and microfilming.
GUIDANCE SIGNS: Signs orientation. Two equilateral triangles drawn arrows or signs focused on, to indicate the blade position on the board.
REFERENCE METRICS GRADUATION: Graduation reference metric. It is a measuring slide of 100 mm in length, divided into centimeters, showing the reduction stems from cases of reproduction.

Altimetry (MAPPING)

scale. is the mathematical relationship between the actual dimensions and the drawing that represents reality in a plane or map.

What is
The map scale is the mathematical relationship between the dimensions in the map, chart or plane and land it represents. By extension can refer to more or less depth of focus on a geographical theme


Representation Scales written as fraction where the numerator indicates the value plane and the denominator the value of reality. For example, the 1:500 scale means that 1 cm of level equivalent to 5 m in reality.
Examples: 1:1, 1:10, 1:500, 5:1, 50:1
If you want to measure the drawing is a surface, be taken into account the relationship of areas of similar figures, eg a square of side 1cm on the drawing.

types of scales

There are three types of scales:

natural scale. It is when the physical size of the object represented in the plane coincides with reality. There several standard formats of plans to ensure that the majority of parts being machined, are naturally drawn to scale, or 1:1 scale

scale reduction. It is used when the physical size of the plane is less than reality. This scale is widely used to represent small components (E1: 2 or E1: 5) home plans (E, 1:50), or physical maps of areas where the reduction is much larger and scales of the order can be of E.1: 50,000 or E.1: 100,000. For the real value of a dimension is multiplied as the plane by the value of the denominator.

Escala de ampliación . Cuando hay que hacer el plano de piezas muy pequeñas o de detalles de un plano se utilizan la escala de ampliación en este caso el valor del numerador es más alto que el valor del denominador o sea que se deberá dividir por el numerador para conocer el valor real de la pieza. Ejemplos de escalas de ampliación son: E.2:1 o E.10:1

Escala gráfica, numérica y unidad por unidad

La escala numérica. representa una relación entre el valor de la realidad (el número a the left of the symbol ":") and the value of representation (the value to the right of the symbol ":"). An example would be 1:100.000, indicating that 1 unit represents 100,000 of the same units (cm, m, km, etc.).

The scale unit by unit. equality is expressed in two lengths: the map (left of the sign "=") and reality (to the right of the "="). An example would be 1 cm = 4 km and 2 cm = 500 m, etc. Finally

graphic scale is a representation of the scale drawn unit by unit where each segment shows the relationship between the length of the representation and reality. An example would be:
0_________10 km
Standardization of scales according to the UNE EN ISO 5455:1996. "Technical drawings. Escalas" we recommend the following standardized scales: Scales
enlargement: 100:1, 50:1, 20:1, 10:1, 5:1, 2:1
natural Scale: 1:1
scale: 1:2, 1:5, 1:10, 1:20, 1:50, 1:100, 1:200, 1:500, 1:1000, 1:2000, 1:5000, 1: 20000

Representation
map The maps
is usually a graphic scale, a small sign depicting a ruler, with the equivalent distance. To calculate the actual distance we measure the distance on the map and compare, that is, measure it with a graphic scale. To move from the actual distance on the map representation we divide by the scale. Keep in mind that whenever we get results in the units where we have taken action.

The larger the denominator smaller the final map that we get, we say that a scale is small when you get a small map, and great when we get large maps to represent the same element.

The different scales allow us to study different phenomena. On a scale of 1:50 and 1:100 phenomena can be studied much detail (you can draw a house, for example). These representations are called specifically planes. With

between 1:5.000 and 1:20.000 scales can represent city street plans. Between 1:20.000 and 1:50.000 counties and municipalities can study. Between 1:50.000 and 1:200.000 can study areas and roads. Between 1:200,000 and 1:1,000,000 can see the countries and their divisions. A 1:1,000,000 scale below we can see continents and even worldwide.

In small maps, under 1:50.000, information that appears on them is not drawn to scale, so that they can not calculate the width of a road, or the radius of a curve, or extent of a city with only multiply the size of the scale drawing.

should also be borne in mind that maps 1:1.000.000 under the center of the map only maintains the equivalence of the scale. The more the edge we are more deformed find. The character of these deformations depends on the type of projection .

The term "scale" is also used in the methodology in the social sciences : Questionnaire scales, when we say for example that values \u200b\u200bof 0 to 5 the importance of a variable.
for the representation of a scale using the formula E / 1 = d / D where E: scale d: distance in the plane, D: actual distance. to find any of the variables is necessary to clear the formula

Many people do not feel comfortable dealing with numbers and have difficulty understanding the meaning of the scale, but play a scale does not necessarily translated into metric units to understand, is simple: if a plan indicates that its 1:50 scale is placed over it, for example, a shoe, and the distance that the shoe cover on the plane means that to cover that distance in reality need shoes as enfilar 50 is used.

TOPOGRAPHY TOOLS










Tape

The tape used in me condition of distances builds in a thin layer of chromium steel or aluminum , or a carbon fiber woven together by a polymer d and Teflon (the latest). The most used tape measures are 10, 15, 20, 25, 30, 50 and 100 meters.
The last two are called a surveyor and built only of steel, because the force needed to tighten it could result in the extension of the same if they were built in a material less resistant to traction. The smallest are
centimeter and even millimeter some with marks and numbers painted or engraved on the surface of the tape, while surveying are marked by copper or brass rivets fixed to the tape every 2 dm , using a rivet slightly larger for odd numbers and a small oval numbered to even numbers. They are usually
protected in a bun made of brass or PVC. The surveyor has two brass handles at each end for precise tensioning and may remove them completely from the wheel for comfort ..








tape measurement




A common problem when measuring a distance with a tape, measure the distance is greater than the length of the tape. To overcome this disadvantage, in surveying applies what is called "Normal Operating Procedure (SOP).
The procediemiento it helps with milestones and a game of cards or ag s UJA surveying (small steel spikes, usually ten, together with a transport ring.)

With Normal Operating Procedure milestones materializes line to be measured, as follows: place a marker at each end of the segment to be measured and then line up (roughly) one or more milestones, the sub-segments so obtained are less than the length of tape available. Once materialized
the line where the tape will, a member of the measuring equipment (from now on the "front"), take a tip tape and play cards, and began to travel the segment to be measured, where the tape is finished will be aligned (by eye) on the other team member (from here on the "defender"), where he nailed the first tab inside the handle that holds in its hands. This procedure is repeated as many times as necessary to reach the other end of the segment.
As progress is made, the striker will be pinning their chips and put defender handle the extreme outside of the chip found, lifting it and putting it into another ring of transport when the striker has lined up and nailed a new tab. In the end they will have the chips that the defender takes his ring (Which will be the number of "bands") and multiply them by the length of the tape to it will add the remaining segment is between the last tab and the pull of arrival, giving the total measured distance.






The Theodolite :
is the universal instrument and is mainly used for measuring horizontal and vertical angles, to measure distances and to prolong stay alienation. The theodolite has a telescope capable of rotating around a vertical axis and a horizontal one is usually equipped with a magnetic compass is mounted on a tripod. The first theodolite was built circa 1571 by Leonard Digges English. It is used for measuring horizontal and vertical angles, and to prolong
lectrotipo alienation, the tellurometer and Distomap.


















Stitches:
are generally about 25 to 35 cms in length, are made of steel rod and provided at a tip end and the other of a ring that serves as their head.






















LEVELS:
A level is an instrument that represents a reference to us respect to a horizontal plane.
This device helps to determine the difference in elevation between two points with the help of a State concerned.
The simplest level is the




















hose level is a transparent tube, water is introduced and both ends are lifted by a simple equilibrium, the water is at the same level at both ends.





























The hand level is too simple an instrument, the horizontal reference is a glass bubble or drop, clisímetro is an improved version incorporating a hand level to make enabling metal transporter tilt measurements and not just drop.












The fixed level is the sophisticated version of the hand level, this bra instead of ERSE hand is placed on a tripod The lens has more gains and the drop is much more sensitive.
This level presents a problem, and that as the device operates must be continually checking and especially when turning, the drop remained focused, this is done with 4 leveling screws which move in pairs, and always maintaining voltage for the appliance does not move ..
This problem was solved with the level swing, which remains a fixed level, but has a screw to adjust the drop each time a measurement is made, greatly simplifying the use of 4 leveling screws, one level is a more accurate tilting level, but its accuracy is mostly just to drop and a plane parallel plate .. A breakthrough was
achieved with the introduction of automatic balancing, leading to


















Automatic Level, its use is based on a gravity pendulum, this steady state is always upright, and with the help of a prism, this will give us the horizontal reference we are looking for. This level has a bubble circular (porthole) that can not be completely focused, but the automatic compensator does just that, to compensate, This advance was so helpful, which was incorporated into more precise theodolites and total stations, even if their performance can vary, the principle remains the same.


















For the advantages automatic levels are most easily found on the market, in features that are be observed when comparing instruments is the magnification of the lens that can be 20x to 32x, this means that both magnifies the image to see through the level, if the distances are short (less than 10 meters) may not be transcendent, but when looking for a graduate State Authority to the millimeter to 100 meters if it is important to have a more level increases, or if it requires great precision even short distances would recommend the 32 increases. Specifications is that the number of increases is linked to the accuracy of the equipment, expressed in millimeters per kilometer round level, so if such a level is accurate to ± 1.5 mm / km, meaning that in a Leveling a mile round trip has an error of plus or minus an inch and a half.
Overall you could say that the range of a level of 20 times is 50 meters, 22x.-65mts, 79mts 24x. ", 26x.-92mts, 104mts 28x.", 30x.-115mts, 125mts 32x., but if you use a high magnification level at distances will more easily short to take readings in the state and possibly more accurately, so if for example you want to level a machine, where distances can not exceed 10 meters, would recommend to use the level of 32 increases, for maximum accurately as possible. While the level
only serves to measure slope, have been recently incorporated a graduation in the pan, allowing for measurements of angles with an accuracy of half a degree, being practical in situ to measure or draw angles not require high horizontal accuracy.
There is a parallel flat plate accessory called the accessory or micrometer can measure to the tenth of a millimeter, but can be placed at any level, is recommended only for levels with 32 increases, this accessory is very helpful for jobs that require much accuracy., in some cases is even advisable to use inbar State Authority to eliminate error due to variation in temperature and expansion of the State Authority of aluminum.




laser levels were still a novelty and some people believe q ue are more precise, but the reality is different, there are only a line projected on a wall, its correct name is crossline are mainly used indoors as outdoors in sunlight is difficult to see the line projected on a wall for example, line which incidentally is between 1 and 2 millimeters wide, so if precision. In one kilometer is 1 centimeter compared to an optical level, laser levels are also holding a sensor, it can be used outdoors and at greater distances, and it is not of the human eye, if not a specialized sensor to see the light laser, there are teams of different prices and details if you purchase a level, make sure that this is a quality and is properly calibrated, otherwise I recommend a level better hose.
not all bad in the laser levels, one of its advantages is that you can use a single person, sets the level at a central point and be measured directly at the points required, also if you have several installers (in frames per example) working at the same time, everyone can have a sensor and be using the same reference at the same time. They are also very practical excavation equipment mounted or flat, eliminating the need to halt the machinery to put a state and make the measurement with a laser level machine operator can know instantly if above or below the desired level .













Finally, there are electronic levels, these levels function as optical them, and additional readings can be made electronically coded State Authority bar, it is convenient, since the measurement is very fast, and eliminating reading errors of assessment or even a finger, since they have memory for storing and processing data on the screen can display a resolution of one tenth of mm, and measure distances with a resolution of one centimeter.
Si bien un teodolito o una estación total se puede usar como nivel, las mediciones no serán tan precisas, siendo que el nivel es un instrumento especializado, pero si no requiere gran precisión. Se puede utilizar una estación o un teodolito ajustando el ángulo vertical a 90 grados.














P G S :
Sistema de posicionamiento global (Global Positioning System), there are two types:

NAVEGADORESGPS . These are more for recreational purposes and applications not requiring high precision, consists of a device that fits in the palm of the hand, with integrated antenna, its accuracy may be less than 15 meters, but if he uses the WAAS system can be of less than 3 meters.
addition to providing our position in the horizontal plane may indicate the rise by the same signal from satellites, some models also have a barometer to determine the height to atmospheric pressure.
models have electronic compass that can determine the "direction motion "(path), ie must be in motion to indicate correctly to where the north.
The GPS satellite signal does not require any payment or rent.




GPS TOPOGRAPHIC
These teams have details from several millimeters to less than half a meter.
There's a band GPS (L1) and two bands (L1, L2), the difference is that for a band GPS ensures pinpoint accuracy for distances less than 40km between antennas, dual-band GPS is up to 300km, while measurements are distances higher, since not guarantee the accuracy of the readings. The GPS surveying
require two antennas, whether the user has both, or only have one and buy the book to an institution like the INEGI or Omnistar (DGPS). We then say that you are working in differential mode.
The difference in price of a GPS in a band against a Two bands can be very large, and more so when the two bands incorporated GPS function RTK (Real Time Kinematic). How to work with computers that do not incorporate RTK function is: move the teams to field, do the readings, but only until it returns to cabinet measurements obtained with an RTK system, data are obtained directly in the field and the high price of these devices is incorporating a computer and a radio communication system between the two antennas.
The GPS does not replace the total station in most cases complementary. It is in very large surveys where GPS is particularly useful, since it requires no line of sight between an antenna and another, in addition to the GPS the major constraint to work alone in rooms with view of the sky, being a bit problematic even when vegetation is tall and dense, but for example a forest or forest opening a clear 5 meters and the measurement is made with the antenna, instead of opening a gap to have sight between the station total y el prisma. Así mismo es común hacer el levantamiento de dos puntos con GPS (línea de control) y posteriormente usar la estación y en lugar de introducir coordenadas arbitrarias introducimos coordenadas geográficas, y todo lo que se levante con la estación estará georeferenciado.
Otro aspecto importante es hacer la diferenciación de un sistema de navegación y un sistema de localización o rastreo, el primero permite que la persona que tiene el dispositivo GPS sepa dónde está y para donde ir, para que una tercera persona lo sepa es otra historia eso ya es un sistema de localización, estos sistemas si requieren una renta o cuota mensual, ya que aun cuando usan un GPS, este solo recibe la señal satellites, we need another cell type device to transmit position to a computer connected to the Internet for anyone to access a page and know where the device.

Jalón

A milestone was originally a stick long wooden , section cylindrical or prismatic
topped by a steel ferrule , where it digs into the ground. Currently, manufactured in steel or fiberglass , in sections of 1.50 m. or 1.00 m. long, plug-in by the hucksters or threadable each other to form a marker of greater height and allow better visibility in forested areas or steep slopes. They are painted (the steel) or formed (the fiberglass) with alternating bands usually red and white 25 cm in length. The colors are due to better viewing in the field and the width of the strips is used to roughly measure by Estadimetría . The milestones are used to mark fixed points in lifting topographic maps, to draw alignments, to determine the basis and to highlight specific points on the ground. Normally, they are an aid to theodolite, the compass , the sextant or other measuring instruments as electronic total station

How To Capturing Shinies On Heartgold



What is an electric bass?

Low began as an instrument electrical muscical four strings, a mix between the guitar and bass, as explained by its original name: bass guitar (in English "bass guitar"). Is a relatively 'young', considering that its creation goes back to mid-twentieth century.
To date the instrument has experienced several changes in its evolution, are seen with greater number of strings (up from 4 may be 5, 6 and occasionally 7), and greater number of divisions or dishes (up to 24 generally, there are more) although there is a variety that does not possess, and are called "Fretless" (literally, "without frets).
The electric bass is built similarly to an electric guitar. It has a solid base (bridge), which are fixed one end of the strings. Below are the strings electromagnetic pills (capsules or microphones), which capture the vibration of the strings, translated into an electrical signal and sent through the line (cable) to the amplifier or speakers. Depending on model, has a rotary knobs (potentiometers) that are used to adjust the overall volume or each capsule, the bass, media and / or acute (also called English tone tone-), and to control effects that you can apply.
The first bass guitar was built in 1951 by Mr. Leo Fender, which he called "precision bass
as they could run more than a bass precison of those times.

or the fretless bass Fretless

is the fretless bass or, as it is known universally as the fretless. For English speakers
exclusive fretless word means exactly that: no frets (fret = contrast, less = absence or lack of something).
A fretless bass is a bass that, like its grandfather bass, fret not, that is, no intonation metal separations between semitones, which technically means it has no bars to set the low end of the string vibration or "node" and allows the "long "of the vibrating string is accurately measured from the bridge to the finger pressing the string. The latter enables the instrument, like classical string instruments like the violin or the aforementioned bass, is not limited to any particular system of tuning. The fretless thus permits the use of so-called microtones and scales that are out of the limitation of the 12 tones traditional bass. Therefore, the fretless bass is the one that gives greater freedom in terms of scales and tones. If a traditional bass we have no choice but to move from G to G # or Gb, a fretless bass can be found throughout the tonal spectrum that exists between the semitones. The expressive possibilities are limitless, making it a favorite of bassists in jazz musicians (as the same Jaco Pastorius, who somehow gave the initial foot in the manufacture of fretless bass) and bears related to the rhythm and blues and funk, among other styles, although there are also significant users in the world of rock and progressive metal, again, thanks to the absolute freedom of the instrument makes use in experimental environments.
has, of course, some disadvantages inherent in its construction. First, since no metal acting as a node, the sustain of the notes is less than a fretted bass with the same characteristics, and the volume they produce is also lower. Sure, it's an entirely solved in modern fretless bass, as the technology of capsules and active electronics has come to fill some lack in terms of power acoustic sound. Another "disadvantage" is that any timber is suitable for a fretless fingerboard, still needed a little more hard wood, ebony typically, to prevent or delay damage to the strings occur on the fretboard. Currently, flatwound strings are used for this purpose to protect the pitch and would enhance a more "dull" and a better slip of the hand.
Finally, we say that the experience and training in both the left (typically pressing the strings on the fingerboard, for lefties, right) and the ear is essential to enjoy and use either a fretless bass. The author of this post had a low of these features when musical life was still very young and frustrated from their lack of perspective and training, felt that the benefits of freedom of the fretless bass tone was the opposite, impediments to performance. Foolishly did not keep such an instrument. Now, over the years, weeps bitterly at night, dreaming about the delicious possibilities of the fretless bass, which ultimately are possibilities to create. The fretless is certainly low for all occasions and for all the bears either. But when it reaches a certain expertise and develop a taste, is a much needed color in the palette.

Netherlands Netherlands assets and liabilities.

How do we know which is which and what are the differences? Is one better than another?

The electronic part of the lower is the determines whether the bass is passive or do anything activo.Primero crucial clarification: It is said that if a low battery takes to feed the preamp. is active ... ¡¡¡!!!! Sometimes you do not and is only a low hybrid as your preamp is active, but their capsules are passive, so when we refer to an active low is when the preamp and capsules need energy (batteries) to function.

Electronics Passive

is the first to be created and installed an electric bass, works as follows: When we play a certain string and produce a frequency, it alters the magnetic field of the capsule, carrying la señal por los potenciómetros para poder regularla y luego sale por el jack que llevara la señal al amplificador, ya que esta señal sale de forma directa, sin amplificar, así que para quepodamos escuchar la señal, primero debemos pasarla por un previo y después a los altavoces. Por lo tanto, estos bajos no necesitan batería para funcionar, es mucho más práctico pero a su vez tiene algunas limitaciones, por ejemplo el control de tono no es tan versátil como el de un bajo activo; generalmente el bajo pasivo se ajusta de una manera y así se deja. Tampoco se recomienda conectar el bajo pasivo directamente a la mesa de mezclas.Un ejemplo de electrónica pasiva seria la de un Fender mexicano o americano no deluxe. Electronic

active:

This emerges in the early 70's. Starting these low, as we said, have a battery in the preamp. But the capsules also take batteries also enhanced. Usually the circuit is activated when you plug the cable into the jack, so it can happen that, for example, to maintain the low connected for long periods without use, you may find the battery, since you used it or not, the circuit was running. (We note that when the battery is low energy signal is weak, distorted, or simply does not exist). The active electronics are very popular because it is very versatile, we can have a wide palette of sounds that can be controlled from our low, and are fit enough to occupy them live and also recording studio, you can send the signal directly to the mixer, since the signal amplified out instrumento.Un own serious example of active electronics of a Status Buzzard.

hybrid electronic :

is not generally known or named, but is more common than we think, in fact, few really have low assets, electronics hybrid is the one composed with a preamp. capsules active and passive, but beware that it can also be Otherwise, the controls are passive and have capsules activas.Un serious example of electronic hybridization of any Ibanez or ESP media.Espero end they have clear differences in this part of the bass, and really understand which is which . Greetings! and welcome your comments.

Classic vs. Modern

the outset, clarify that these categories - classic, modern - not intended to be accurate or precise, but are terms used by the bearish enough to differentiate both construction and design approaches instrumento.Quizás our most useful in clarifying and somehow know de qué estamos hablando sea ejemplificar: en el lado de los bajos “clásicos” tenemos primero que nada los Fender, sobretodo los modelos presentados en el artículo anterior, pero también otros de inspiración similar como los Ernie Ball Music Man, modelos Les Paul y SG de la Gibson (sí, existe el bajo Les Paul, y suena de maravillas), sin dejar de mencionar, por supuesto, el inmortal Rickenbacker. Del otro lado, el de los “modernos”, tenemos marcas y modelos como Ibanez, Warwick, Spector y otras afines. Nuevamente, el listado anterior de ninguna manera agota los modelos y marcas de uno y otro tipo, ya que el universo actual de los bajos eléctricos es vasto e infinito.
De acuerdo ya en as to what we mean by each category, let's concentrate on its main features:

"classic":

The classic basses first, although it seems obvious, are the oldest brands and therefore, the models are all very directly related to the first electric bass (Fender precission, above). The exception is Rickenbaker, a mark of character quite unique in its design, how to produce (to this day most of the process under which each is hand made, so that while the orders are delayed rather, it is guaranteed in any way the quality of the finish, finishing, and electronics of each piece). However, even this strange "big brother" shares certain characteristics with others, so we will specify:
- The scale (distance between the nut and bridge) is long, between 34 and 35 inches, which provides great sustain and heavy bass, powerful and very present, since the string tension is higher.
- The bodies of the classic low tend to be large and heavy, very solid wood, which, apart from giving a very characteristic strength to the construction of classical models, helps the fat sound of them.
- While all brands mentioned in the classics have their lower models with active electronics, bass classics are passive electronics and capsules, that is, they use the action of the magnets of the capsule only to produce volume and tone. This underlines, above all, the sound of the woods, though the latter is debatable.
- Low mast classics are usually wide and four strings, true to their heritage of traditional bass that, better or for worse, it emulates. This makes them very favorite tools of bass passed to the world of electric bass, for example, because the differences are smaller in size and position of the strings.

Models "Modern"

Again, it is clear that the category of "modern low" corresponds to newer brands on the market, at least newer than the classics, such as Warwick, Ibanez, Schecter, Spector and ESP, to name a few. Eye, the distinction is only temporary or historical (as Music Man, for example, is a brand that dates back to the 50's as Fender, but it is modern contemporary), but mainly on design. That said, we can plant the modern low differ substantially in their design and electronics, which are separated radically classic models:
- The scale is maintained in most cases, but there are models that this reduces from 34 to 32 inches, and in some modern low takes up 30 inches short ranges, in the style of old classics as a Hofner violin bass (the Mc Cartney) or the Fender Mustang Bass. This decrease in length scale mainly leads to greater comfort for the interpretation, especially for bassists with smaller hands.
- The bodies presented a major innovation for the classic models, they are lighter, more stylish and comfortable for the performer. This also has an effect on the tone of the instrument, which EINSTALL somewhat more defined, but you lose the extreme depth of the classics. In contrast, the low for this feature, are more delicate
- Another important innovation is in the neck, thinner and action (string height on the fingerboard) faster, with dishes usually a little smaller, which aid at the speed of interpretation, again, for the sake of convenience. Moreover, these models begin to appear options 5, 6, 7, 8 and 12 strings, no octaves, which provides an extended range of the instrument.
- electronics plays an important role here, with mostly electronic active, ie a system of equalization and even on more expensive models, pre-amp specifically dedicated for that purpose, whose characteristics require the use of an independent power source, usually one and even two 9v batteries, depending on system. These circuits can control the pitch in various frequency bands (bass, mid and high), giving more power and presence to the instrument signal, and even act as a pre amplifier built in (making it necessary, theoretically, only one amplifier able to ring, without pre-amplification stage of a traditional bass amp, could you direct connect PA system and play a room without an amplifier, for example). Some purists say that these circuits dress too natrual tone of wood and strings, making them more "artificial." Again, this is a matter of discussion.
As final words, that as long as the ears and not what you send "read". Probably in an indie rock or classical inspiration, perfect bass is a Fender or a Rickenbacker, while a metal band is the most appropriate hipertécnico low ESP or Schecter, which by its versatility and lower neck width allows implemented more neatly. Much can be said about it and there is no absolute truth: John Myung, Ibanez user recognized for its swift action thin neck, active electronics and precise tone, all modern features, radically changed their sound and now uses a Music Man Bongo 5-String, not 6 as before, that while a modern bass, it has the neck and body characteristics more related to a classic. And John Paul Jones, Led Zeppelin bassist, came not with a Jazz Bass or Bass precission on stage for the return of the legendary band: in his hands is a modern bass, active electronics and thin neck, playing classics such as "dazed and confused "without losing an ounce of weight. Everything is possible in the vineyard of the electric bass, My friends Jaclk Bruce, bassist for Cream, he played in the golden era of the band with a Gibson SG, under heavy by definition. In the reunion tour, a few years ago in his hands was a modern, comfortable, active and Warwick ...

P-Bass v / s J-bass

These are 2 powers created by Don Leo Fender Precision Bass and Jazz from Bass.Para worth mentioning that the Precision Bass was the first electric bass guitar created in history, while the Jazz Bass, the model is conceived as "deluxe" from below Precision.A I will present a table with some characteristics of the P-bass and J-can bass.Como see, the differences are not as noticeable in construction and hardware environment (in fact assumes that the J-bass is the evolution of Precision) but the results are remarkably different. Let us describe the sound of each bass.
The P-BASS is characterized by a sound more responsive in terms of means-serious and serious. It is less bright than the Jazz Bass, and larger mast makes it ideal for those who prefer a classic bass with a more slowly than the Jazz. Your pills are much less noisy than a Jazz. This bass is ideal for rock, since it has a lot of punch, is ideal for use with a chisel, and even to be "slap." Perhaps Precision great but the capsule is that its only split coil hum-canceling, gives little versatility of tones.
On the other hand, J-BASS has a warmer sound "heavy" and less aggressive than a Precision Bass, which makes it ideal for performers who played with the fingers, is much more versatile the Precision, since it was incorporated an additional pickup near the bridge, thus increasing its resources from one type sounds "bright" to more "thick." Cons that could be this low is that your pills are something ruidosas.En end, much has been written on the subject and could talk much more about these 2 powers in the world electric bass, but in a nutshell we have the most relevant. In conclusion, we could say that the P-bass is the low rocker par excellence, while the J-bass is the low of modern jazz. Notable Users
Precision Bass: Steve Harris (Iron Maiden), Duff McKagan (Guns N 'Roses / Velvet Revolver), Nick Oliveri (Queens of the Stone Age), Zeta Bosio (Soda Stereo / Catupecu Machu), Sting (The Police / Soloist), Geezer Butler (Black Sabbath), Cliff Burton (Metallica) and many others.

Jazz Bass: Jaco Pastorius (Weather Report / Soloist), Marcus Miller (Soloist), Geddy Lee (Rush), Flea (Red Hot Chili Peppers), Tim Commerford (Rage Against the Machine / Audioslave), John Paul Jones (Led Zeppelin), Dirk Lance (Incubus), Juan Alderete 8The Mars Volta), John Entwistle (The Who).
As can be seen, both basses are very present in the history of popular music and especially in the rock world. Both sound like instant classic, and despite its high price and features at times uncomfortable for many bass players, is an investment, either, that any serious bass player should do at some point in their life as a journey to Mecca for a Muslim or the Vatican for a Catholic, a matter of historical value, but also to obtain a sound and character that no other instrument can imitate. Many say that the "majority" of the bass is achieved only with a Fender in his hands. It is an object of discusión.Saludos.

Parts of electric bass

As we see, under construction is quite similar to that of an electric guitar, below give a brief description of the parties:
socket: this part of the low helps us to refine our bass guitar, for example if we raise the note of the string, headstock move clockwise to raise the tension of the string and so the note goes up, so instead, giving you less stress, get a low in the note of the string.
socket blade, as you can see, the function of this piece is to hold the sockets, also usually printed with the brand and model of low cuestion.Mástil: The mast can be bolted to the body (bolt-on), or be of the neck-thru body (where the neck and body are made from a single piece of wood). The advantage of the latter is that it allows the sound vibration is transmitted evenly and without changes in body neck, there to be picked up by the pads the same way.
Frets: A fret is the gap that exists on the fingerboard of the neck of many stringed instruments, in most modern instruments the frets are thin metal strips embedded in the fingerboard. The most common is that the frets divide the fingerboard into semitone, a contrast equivalent to one semitone.
Pickups: are electromagnetic coils that capture the string vibration and turn it into a signal that can play the amp. Basically we can differentiate these types of pills that are most used in the low : - Single-coil : pills are most common and distinctive sound and classic. Shines through his means very stuck, in fact it says it has sound too "nasal". This type of pills found primarily in the most the Jazz Bass and some precission. Against these pills are likely to make a lot of buzz that makes them very noisy and annoying for the bass player who chooses to use .- Humbucker: are two single-coil attached to the coils in opposite directions and one of the two magnets invested. They get a much more powerful and with the improvement compared to the single no longer hum of any kind, are very quiet pills and can be found for example in the Music Man or some Warwick .- Stacked humbucker : Seems a single-coil, but in reality are two, one mounted on the other to eliminate hum. Do not take a sound as thick as a typical humbucker, but their sound is still great and retains many qualities of this .- Soapbar: English Literally, bar soap, because the rectangular shape of the plastic. Below this may be any type of pickup. This leaves more space for active preamp or larger magnets for powerful sound inside the case.
Strings: There are four basic types of string bass "roundwound : they are the most common, of 'twisted' or circular wound around a core of resilient material, usually steel. They give a bright sound that is sustained for longer after the string down (sustain).
-flatwound : are twisted plane and deliver a sound off and with less "sustain"
-halfwound : not used as frequently as the two previous types are a hybrid, since they have the upper half of the twisted cord and the lower level of normal twisted.
There are other less commonly used types of rope, as groundwound , circular twisted ropes which have been sanding it until it was flat, or tapewound , twisted ropes generally circular coated nylon, which contributes to give a darker tone and feel more pleasant, like the strings of twisted plane.
Body: The body of a bass usually made of wood and the choice of it is very important in the sound of the instrument (It should be noted that there are bodies and necks of graphite - Steinberger, Modulus Graphite - and some acrylic or plastic composites). Currently used (by limiting the list to wood), especially poplar, alder, maple (in English, "maple") and basswood for the body and maple, rosewood and ebony wood rail for the mast, among other several American woods, and a wide range of African woods such as bubinga and wenge.
Potentiometers: are what we generally help regulate the tone and volume.
Bridge: is where you place the bass strings, usually in low economic, real murderers are usually strings.
