Boss BOSS 50th Anniversary Super Overdrive - SD-1-B50A

For nearly five decades, BOSS has defined overdrive pedal excellence, beginning with the legendary OD-1 in 1977 and perfecting the formula with the SD-1 Super OverDrive in 1981. This 50th anniversary edition honors that legacy with premium aesthetics—metallic finish, gold-capped knobs, silver thumb screw, and commemorative emblem—while preserving the circuit that has powered countless professional and amateur rigs. Each unit carries a unique 4-digit serial number and arrives in custom packaging, making this strictly limited release (7,000 units worldwide) a significant addition to any collection. The same responsive gain staging and tonal shaping that established the SD-1 as an industry standard remains unchanged, ensuring both sonic authenticity and investment value.
