String effect on a single coil (electric guitar). The coil is connected to a multimeter that indicates the voltage changes wh the string moves. This signal is normally st to an amplifier.
A single coil pickup is a type of magnetic transducer, or pickup, for the electric guitar and the electric bass. It electromagnetically converts the vibration of the strings to an electric signal. Single coil pickups are one of the two most popular designs, along with dual-coil or humbucking pickups.
In the mid-1920s George Beauchamp, a Los Angeles, California guitarist, began experimtation with electric amplification of the guitar. Originally using a phonograph pickup assembly, Beauchamp began testing many differt combinations of coils and magnets trying to create the first electromagnetic guitar pickup.

His earliest coils were wound using a motor from a washing machine. Later on he switched to a sewing machine motor, and evtually used single coiled magnets.
Beauchamp was backed in his efforts by Adolph Rickbacker, an gineer and wealthy owner of a successful tool and die business. Beauchamp evtually produced the first successful single coil pickup. The pickup consisted of two massive U shaped magnets and one coil and was known as the horseshoe pickup.
The two horseshoe-shaped magnets surrounded the strings that passed over a single core plate (or blade) in the cter of the coil.
Single Coil Guitar Pickup
The Gibson Guitar Corporation introduced the bar pickup in 1935 for its new line of Hawaiian lap steel guitars. The pickup's basic construction is that of a metal blade inserted through the coil as a shared pole piece for all the strings. A pair of large flat magnets were fasted below the coil assembly.
The ES-150 was outfitted with the bar pickup. Jazz guitar innovator, Charlie Christian, began playing an ES-150 in the late 1930s with the Bny Goodman Orchestra. This caused the popularity of the electrified guitar to soar. Due to Christian's close association with the ES-150 it began being referred to as the Charlie Christian Model and Gibson's now famous bar pickup as the Charlie Christian pickup
These pickups have a large, flat coil with adjustable steel screws as pole pieces, and a pair of flat alnico bar magnets lying under the coil bobbin. The adjustable pole pieces pick up the magnetism from the magnets. Moving the screw closer or further away from the magnet determines signal strgth, thus tone as well. There are two variations of P-90 pickup that differ mainly by mounting options:
Frying Pan (guitar)
The Fder Telecaster features two differt single coils. The neck pickup features a metal cover and produces a mellower sound, while the bridge pickup has exposed pole pieces and produces an extremely twangy, sharp tone with exaggerated treble response,
Because the bridge pickup is mounted on a steel plate. These design elemts allow musicians to emulate steel guitar sounds, making it particularly appropriate for country music.
The Fder Esquire has a variation to the Vintage wiring scheme by using the scheme on a single pickup. This gives a treble cutoff in the first position, normal in the middle position, and a tone control cutoff in the third position.
Gibson Es 335
The guitarist can control which pickup or combination of pickups are selected with a lever switch. The pickup positions are usually referred to as the bridge, middle and neck pickups based on their proximity to those parts of the instrumt. The neck pickup typically has the lowest output, with the most mid-range and bass response, whereas the bridge pickup has the higher output (because the strings at the bridge move less) and the greatest treble response, with a slight twang to it. The sound of the middle pickup is similar to that of the neck pickup, albeit with slightly less bass and more treble. However many players, such as Ritchie Blackmore, find it somewhat of an obstruction to the picking hand, so loos the mounting screws such that it lies flush with the pickguard.
Modern Stratocasters have five-position pickup selector switch. Positions 1, 3 and 5 activate only one pickup (bridge, middle or neck respectively), while positions 2 and 4 activate a combination of two pickups (bridge and middle, or middle and neck, respectively). Some pickup sets have a reverse wound and reverse polarity middle pickup that wh in combination with the normal bridge or neck pickups will cancel electromagnetic interferce (noise/hum) which single coil pickups suffer badly from. The sonic effect of positions 2 and 4 is sometimes referred to as a quack or notch positions, and some guitar notation includes directions to use these pickup combinations. One example is Sultans of Swing by Dire Straits which is played in position 2 (bridge and middle).
Two types of noise afflict magnetic guitar pickups. Hum is caused by magnetic fields due to power frequcy currts in electrical equipmt, whereas buzz is propagated as radio transmissions and sounds more like static. The sources of buzz are many, but one example is an AC power tool with a brush motor. The brush makes and breaks electrical contact with the commutator segmt several thousand times a second at variable frequcy depdt on load thus causing radio frequcy noise.

The search for an acceptable solution to mains hum gained new impetus around 1995 as guitar players became increasingly intolerant of degraded stacked single-coil sound. Fder was researching new techniques to solve the loss of tone around that time and evtually came out with their Vintage Noiseless design around 1998.This article has multiple issues.

A pickup is a transducer that captures or sses mechanical vibrations produced by musical instrumts, particularly stringed instrumts such as the electric guitar, and converts these to an electrical signal that is amplified using an instrumt amplifier to produce musical sounds through a loudspeaker in a speaker closure. The signal from a pickup can also be recorded directly.

The first electrical string instrumt with pickups, the Frying Pan slide guitar, was created by George Beauchamp and Adolph Rickbacker around 1931.
A typical magnetic pickup is a transducer (specifically a variable reluctance ssor) that consists of one or more permant magnets (usually alnico or ferrite) wrapped with a coil of several thousand turns of fine ameled copper wire. The magnet creates a magnetic field which is focused by the pickup's pole piece or pieces.
The permant magnet in the pickup magnetizes the guitar string above it. This causes the string to gerate a magnetic field which is in alignmt with that of the permant magnet. Wh the string is plucked, the magnetic field around it moves up and down with the string. This moving magnetic field induces a currt in the coil of the pickup as described by Faraday's law of induction.

The pickup is connected with a patch cable to an amplifier, which amplifies the signal to a sufficit magnitude of power to drive a loudspeaker (which might require ts of volts). A pickup can also be connected to recording equipmt via a patch cable.
The pickup is most oft mounted on the body of the instrumt, but can be attached to the bridge, neck or pickguard. The pickups vary in power, and they vary in style. Some pickups can be single coil, in which one coil picks up the sound of all strings, while other pickups can be double coil humbuckers. A special type of humbucker characteristic for Precision type bass guitars is called split coil pickup: two coils, each of them picks up differt strings, on a 4-string bass, one coil the E and A string, the second coil the D and G string.
The pickup is one of the most important aspects to distinguishing an electric guitar's sound. Most guitar models have a distinction in pickups, which act as a new selling point for guitar companies.

Pickups have magnetic polepieces, typically one or two for each string, with the notable exceptions of rail and lipstick tube pickups. Single polepieces are approximately ctered on each string whereas dual polepieces such as the standard pickups on the Fder Jazz Bass and Precision Bass sit either side of each string.
On most guitars, the strings are not fully parallel: they converge at the nut and diverge at the
