A pickup can also be connected to recording equipment via a patch cable. The pickup is connected with a patch cable to an amplifier, which amplifies the signal to a sufficient magnitude of power to drive a loudspeaker (which might require tens of volts). Typical output might be 100–300 millivolts. This moving magnetic field induces a current in the coil of the pickup as described by Faraday's law of induction. When the string is plucked, the magnetic field around it moves up and down with the string. This causes the string to generate a magnetic field which is in alignment with that of the permanent magnet. The permanent magnet in the pickup magnetizes the guitar string above it. The magnet creates a magnetic field which is focused by the pickup's pole piece or pieces. Acoustic guitars, upright basses and fiddles often use a piezoelectric pickup.Ī 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 copper wire. Most electric guitars and electric basses use magnetic pickups. The first electrical string instrument with pickups, the " Frying Pan" slide guitar, was created by George Beauchamp and Adolph Rickenbacker around 1931. The signal from a pickup can also be recorded directly. The bridge (right) pickup is a humbucker and the neck (left) and middle pickups are single coils.Ī pickup is a transducer 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.
