This is essentially the same pedal as the Big Box Tone Boost in one of my new, smaller custom made stainless steel enclosures, with new artwork. This is a simple yet VERY effective 1 transistor subtle to high gain boost/overdrive that can push any nice valve amp into saturation and has a very usable 1 transistor active tone control based on those early treble boost circuits made on both sides of the Atlantic back in the 60's. With 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.
