This is a copy of the second series FUZZrite pedal made by Mosrite in the late 60's and now in my new smaller stainless steel "mini" enclosures. I tried to model it as closely to the original as possible, with an adjustment for volume and depth. It is powered by a "Boss" compatible adaptor and has LED and true bypass...
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.
