From the post
Here's a pretty unique fuzz from Mid-Fi. Built around a dual opamp, the Demo Tape Fuzz recreates the sound of a guitar being played directly into an old 4-track cassette deck. It features a 2-band EQ in addition to the Volume and Trim (gain) controls. I've laid it out for board mounted right angle PCB pots mounted from the solder side.
