Pickup (music Technology)
A pickup is an electronic device that converts energy from one form to another that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. The signal from a pickup can also be recorded directly. The first electrical string instrument with pickups, the " Frying Pan" slide guitar, was created by George Beauchamp and Adolph Rickenbacker around 1931. Most electric guitars and electric basses use magnetic pickups. Acoustic guitars, upright basses and fiddles often use a piezo electric pickup. Magnetic pickups A typical magnetic pickup is a transducer (specifically a variable reluctance sensor) that consists of one or more permanent magnets (usually alnico or ferrite) wrapped with a coil of several thousand turns of fine enameled ...

Permanent Magnet
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called Ferromagnetism, ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth element, rare-earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all oth ...

Fender Precision Bass
The Fender Precision Bass (or "P-Bass") is a model of bass guitar, electric bass guitar manufactured by Fender Musical Instruments Corporation. In its standard, post-1957 configuration, the Precision Bass is a solid body, four-stringed instrument usually equipped with a single split-coil humbucker, humbucking pickup and a one-piece, 20-fret maple neck with rosewood or maple fingerboard. Its prototype was designed by Leo Fender in 1950 and the Precision was brought to market in 1951. It was the first electric bass guitar to earn widespread attention and use, remaining among the best-selling and most-imitated electric bass guitars with considerable effect on the sound of popular music. Leo Fender designed the Precision bass for big band guitarists. Kansas City–based Roy Johnson of Lionel Hampton's big band was the first bassist to use the Precision in a concert setting. Music critic Leonard Feather wrote about this new development in ''Down Beat'' magazine, expressing surprise at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fender Jazz Bass
The Fender Jazz Bass (often shortened to "J-Bass") is the second model of Bass guitar, electric bass guitar created by Leo Fender. It is distinct from the Fender Precision Bass, Precision Bass in that its tone is brighter and richer in the midrange and treble with less emphasis on the Harmonic series (music), fundamental frequency. The body shape is also different from the Precision Bass, in that the Precision Bass has a symmetrical lower bout on the body, designed after the Telecaster and Stratocaster lines of guitars, while the Jazz Bass has an offset lower bout, mimicking the design aesthetic of the Fender Jaguar, Jaguar and Fender Jazzmaster, Jazzmaster guitars. History First introduced in 1960 as the Deluxe Model, it borrowed design elements from the Fender Jazzmaster, Jazzmaster guitar. It was renamed the Jazz Bass as Fender felt that its redesigned neck—narrower and more rounded than that of the Precision Bass—would appeal more to jazz musicians. The Jazz Bass has tw ...

Lipstick Pickup
A lipstick guitar pickup is a form of single-coil magnetic guitar pickup, having its electronics totally encased in a chrome-plated metal tube. The lipstick-tube pickup was first introduced by Danelectro on their line of electric guitars. The original lipstick-tube pickups were, in fact, manufactured using real lipstick tubes, and were featured on Danelectro, Danelectro's Coral series, and guitars that were later marketed through Sears, Roebuck and Company department stores under the name Silvertone. These pickups continue to be featured on Danelectro and other guitars. Current production pickups are not made using lipstick tubes, but tubes manufactured specifically for guitar pickups. Construction Unlike a traditional guitar pickup that uses a plastic or fiber bobbin as a form for winding its coil, the lipstick-tube pickup has its coil wrapped around an alnico VI bar magnet, and then wrapped in tape, usually a cellophane-type tape on vintage units, before being inserted int ...

Millivolt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. It can be expressed in terms of SI base units ( m, kg, s, and A) as : \text = \frac = \frac = \frac = \text\text^2\text^. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, s, and A) as : \text = \frac = \frac = \frac = \text\text^2\text^. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalen ...

Root Mean Square
In mathematics, the root mean square (abbrev. RMS, or rms) of a set of values is the square root of the set's mean square. Given a set x_i, its RMS is denoted as either x_\mathrm or \mathrm_x. The RMS is also known as the quadratic mean (denoted M_2), a special case of the generalized mean. The RMS of a continuous function is denoted f_\mathrm and can be defined in terms of an integral of the square of the function. In estimation theory, the root-mean-square deviation of an estimator measures how far the estimator strays from the data. Definition The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or the square of the function that defines the continuous waveform. In the case of a set of ''n'' values \, the RMS is : x_\text = \sqrt. The corresponding formula for a continuous function (or waveform) ''f''(''t'') defined over the interval T_1 \le t \le T_2 is : f_\text = \sqrt , and the R ...

Pole Piece
A pole piece is a structure composed of material of high magnetic permeability that serves to direct the magnetic field produced by a magnet. A pole piece attaches to and in a sense extends a magnet#Modelling magnets, pole of the magnet, hence the name. Pole pieces are used with both permanent magnets and electromagnets. In the case of an electromagnet, the pole piece or pieces simply extend the magnetic core and can even be regarded as part of it, particularly if they are made of the same material. In the case of a permanent magnet, the distinction between the magnet itself and the pole piece or pieces is more clear cut. Materials The traditional material for pole pieces was soft iron. While still often used with permanent magnets, soft iron suffers from eddy currents which make it less suitable for use with electromagnets, and particularly inefficient when the magnet is excited by alternating current. Shapes and forms Pole pieces take many shapes and forms depending on the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Field
A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, electric currents, and electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function (mathematics), function assigning a Euclidean vector, vector to each point of space, ...
