Overdrive effects pedal for electric guitar or bass guitar that is a highly unique and massively tweaked version of the most famous overdrive ever created and is an ideal tool for shaping and creating unique mid heavy tones for almost any need or genre. It has the core tone of the version one and retains the simple Volume, Tone, and Drive knobs. However, it also features an added Clean knob to blend in any amount of clean signal to the tone. The simple 2-position "Proof" toggle provides everything from low gain amp-like breakup with powerful coloured boost settings to grinding, heavy overdrive that reaches to the very edge of cranked amp distortion. The pedal uses an internal 9V to 18V charge pump that allows it to run on normal 9V but converting it internally to 18V for an enormous amount of headroom, added low-end, and more overall punch. It consumes less than 100mA, and measures 56 x 109 x 38 mm.
