This is my homage to the truly great Husker Du and is a take on the classic seventies and eighties distortion that Bob Mould used in this band. It's such a great little circuit that pushes into very nice soft clipping and on into very harmonic square wave. The original "block logo" version got silicon diodes. 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.
