Boss SD-1 40th Anniversary Limited Edition Super Overdrive Pedal
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.
To celebrate 40 years of continuous SD-1 production, BOSS has created a limited edition anniversary version that's available throughout 2021. This commemorative pedal features a black body with yellow lettering, gold-capped knobs, and a vintage silver thumbscrew for the battery compartment, and comes in a box with a special 40th anniversary logo.
