This is my take on the classic seventies and eighties distortion as used by SO MANY bands. It's such a great little circuit that pushes into very nice soft clipping and on into very harmonic square wave. The original "script logo" version has germanium clipping diodes and then in the eighties the "block logo" version got silicon diodes. My Tym version has a small toggle to choose either germanium OR silicon, essentially giving you both versions in one pedal. Mine uses the essential LM741 IC for authentic tone. It also has an LED, a BOSS style adaptor and true bypass, none of which the original had.
My designs are inspired by the classic old units but with modern components and appointments and many options like true bypass or non-true-bypass switching, LED's, added "active" tone controls, boosts and "Boss" compatible 9-volt adapters. NONE of my pedals use batteries.
