Why does korn have a bass clacking sound to the bass?

The bass clacking sound in Korn's music is a result of the way their bassist, Fieldy, plays his instrument. Fieldy uses a slap-and-pop technique, which involves slapping the strings with his thumb and pulling them with his fingers. This creates a percussive sound that is often heard in funk and slap metal music.

Fieldy's bass clacking sound is a key part of Korn's signature sound. It gives their music a unique and aggressive edge that has helped them to stand out from other nu metal bands.
