Boss's Legendary Super Overdrive Sound
Since its release in 1981, the workhorse SD-1 Super Overdrive has been the core gain pedal for generations of players across every musical genre. Based around the revolutionary asymmetrical clipping circuit from the OD-1 Overdrive - one of the three original BOSS compact pedals from 1977 - the SD-1 delivers rich, smooth and highly musical overdrive tones that continue to inspire guitarists everywhere.
