Single Coil Pickups
A single coil pickup is a type of magnetic transducer for the electric guitar and electric bass. It electromagnetically converts the vibration of the strings to an electric signal. A single-coil pickup has only one coil of wire. It may have a single magnet, a single magnet with screws for adjustable pole pieces, or a separate magnet for each string. They are responsible for the “hum” sound. Single-coil pickups are common on Fender guitars such as the Stratocaster and Telecaster, who are common in rock, country, and pop.

Humbucker
A conventional humbuckeror Humbucking pickup that uses two coils, both generating string signal. Humbuckers have high output since both coils are in series and because the magnetic circuit is low loss. Like a single-coil pickup, a humbucker induces a slight magnetic field around the strings, which in turn induce an electrical current on the coils as the strings vibrate. But since the two coils are of reversed polarity and reverse-wound and connected in series, noise and interference is significantly reduced via common-mode rejection. They get their name because they cancel out a large ...
