A humbucker pickup is a type of electric guitar pickup designed to reduce unwanted noise and interference. It consists of two coils wound in opposite directions, which cancels out electromagnetic hum while amplifying the desired sound. This design allows for a thicker, warmer tone compared to single-coil pickups. Humbuckers are commonly used in various music genres, especially in rock and blues. They are known for their ability to produce a powerful sound with increased sustain, making them popular among guitarists who seek a fuller tone. Many famous guitarists, such as Jimmy Page and Slash, favor humbuckers for their signature sound.
