As the innovators of the Black and White Nylon Tape Wound bass set, La Bella introduces the Copper White Nylon Tape Wound Series. Unlike the classic White Nylon Tape Wounds, the new Copper White Nylon Tape Wound strings are made with a transparent nylon wrapped over copper underlays. The result is a warmer and more supple tone, while still allowing players to effortlessly glide from note to note.

If you’re looking for a set of bass strings that growl like a beast, this warmer alternative is for you!
