A humbucker is a type of electric guitar pickup designed to cancel out electromagnetic interference, which reduces unwanted noise and hum. It consists of two coils wound in opposite directions, allowing it to pick up the vibrations of the guitar strings while minimizing background noise. This design makes humbuckers popular in various music genres, especially in rock and jazz. Humbuckers are often found in guitars made by brands like Gibson and Fender. They provide a thicker, warmer sound compared to single-coil pickups, making them ideal for players seeking a richer tone. Many guitarists appreciate their versatility and ability to handle high gain without feedback.
