OD-3 OVERDRIVE PEDALNewly developed Dual-Stage Overdrive Circuit offers a level of sustain and compression unmatched by any overdrive pedal in history. Dramatically increased full bass response and improved dynamics yield a ''bigger'' sound than any previous BOSS overdrive PedalDynamic, non-muffled tones reminiscent of classic overdriven ''stack'' amps. Straightforward Drive, Tone and Level controls. A New Level of Rich, Dynamic Overdrive from the Company that Started it All! In 1977, BOSS introduced the now-legendary OD-1~the world's first compact overdrive pedal for guitarists. The rich, warm tones that this stompbox produced immediately set it apart from the harsh distortion boxes that had come before it. On the 20th anniversary of BOSS compact pedals, we proudly introduce the OD-3 OverDrive, giving guitarists a greatly expanded range of smooth overdrive tones and improved response while staying true to the original.
