Pickups that are coupled together to get a certain sound.
Two single coil pickups, wired side by side so a that the electronic hum you get with most single coil pickups is canceled out.
Using two coils in a pickup makes it a humbucker: It's called a humbucker because the way it's made reduces hum and noise while creating different tones. Some guitars can have just single-coil pickups, just humbuckers, or both.
A noise canceling twin coil pickup normally associated with Fender.
A conventional humbucker (or Humbucking pickup) is a type of electric guitar 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. Since the two coils are of reversed polarity and reverse-wound and connected in series, noise and interference is essentially 'canceled out' through a differential amplifier.
