The design are fairly simple: 5 silicon jFet transistors opamp in a 3 stages working in a combined effort that amplified the source to a bend of harmonies. That is a 6 knobs function distorsion: the basic 3 bands EQ, Treble, Mid and Bass, a Drive, a Voice and a Level. The Voice and the Mid are of key importance for they giving you the scope and range you can get with that cool tool. Because transistor pedals have only one sound and one tone, I built that pedal in order to allow diverse variations. You will have to fine-tune it to get the tone you want.
