Mad professor ”1” ... Like the legendary tone of EVH’s ”brown sound“ this pedal produces intense drive while retaining high definition. The pedal also includes a built-in reverb circuit to add ambiance and depth to your sound. 1's gain ranges from medium to very heavy distortion and the “brown” knob controls the amount of harmonic overtones in the distortion.

Pretty much mint condition with original box, only played in attic and never gigged. Quite rare to find these days especially in this condition.
