Vintage Black Beauty capacitors, 160P. Functionality confirmed with a tester and guitar; readings are good. .047 400v, a standard and popular value. Ideal for single-coil guitars, voltage is optimal. Also suitable for other electronic components. 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 bite, Bumble Bees are the choice, but the straight, uncolored sustain of Black Beauties makes them popular.
