Определение humbucker в Английский Язык Английский Язык словарь
A pickup, on an electric guitar, that has a pair of coils of reverse polarity connected in series - to "buck" the "hum"
(Muzik) 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 significantly reduced via common-mode rejection. They get their name because they cancel out a large proportion of the mains induced hum (they "buck the hum") normally experienced with single coil pickups
A guitar pickup which uses two identical opposing coils, each operating in an opposing magnetic field to create a pickup with no hum (It bucks the hum hence humbucker)
Effectively two single coils made into a double (see description of pickup for more details)
