Since 1973, BOSS has pioneered the development of unique and innovative guitar gear for players of all styles. The iconic compact pedal design was unveiled in 1977 showcasing the game-changing OD-1 OverDrive. Subsequently, in 1981, BOSS released the SD-1 Super OverDrive featuring the added benefit of a tone control. Remaining in production ever since, this workhorse gain machine has continuously graced the pedalboards of beginners and pros the world over.

Marking the celebration of BOSS's 50th anniversary, the limited-edition SD-1-B50A Super OverDrive sports a metallic finish; silver thumb screw; gold-capped knobs; and commemorative 50-year anniversary emblem. Appearing in exclusive livery with a dedicated 4-digit serial number and bespoke packaging, the SD-1-B50A features the same beloved circuitry as the standard production SD-1 Super OverDrive. This collectible version is available in strictly limited numbers of no more than 7,000 units worldwide.
