The Business Card Fuzz (BCFUZZ) is a fuzz pedal that is designed to be simple and easy to build. It is based on the NPN style Fuzz Face circuit and is intended to be used with Si NPN transistors, although it can also work with Germanium types if they are properly specified.

The BCFUZZ has three controls: Fuzz, Level, and Squish. The Fuzz and Level controls are standard controls found on most fuzz pedals and allow you to adjust the amount of fuzz and the overall volume level. The Squish control is a unique feature of the BCFUZZ and adds resistance to the feedback path between two transistors, causing the fuzz to compress even further. At the highest setting, the fuzz will squish down into bumble fuzz tones.
