Pickup (music technology)

Captures vibrations produced by musical instruments Three magnetic pickups on a Peavey Raptor with the pickup configuration of a fat-strat (H-S-S). The bridge (right) pickup is a humbucker and the neck (left) and middle pickups are single-coils. A pickup is an electromagnetic transducer that converts energy from one form to another that captures or senses mechanical vibrations produced by musical instruments, particularly string instruments such as electric guitars, 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 piezoelectric pickups.[citation needed] 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
