Black Beauty capacitors are famous for being original parts in old Gibson guitars. It's not just that old Gibson enthusiasts like to talk about them; they actually dramatically change the sound. Black Beauties have little distortion and a very pure sound quality. If you're looking for a biting, distorted sound, Bumble Bees are the way to go, but the straight, uncolored tone of Black Beauties is popular.
