Boss - Super Overdrive (USED)

Debuting in 1981, the Boss SD-1 is the second longest running Boss pedal and a pioneer in the world of compact overdrives. Even today, people still use it as an alternative to a Tube Screamer. Why pay $200 for a boutique overdrive when you can dial in the right amount of crunch and dirt for less with time-tested, original overdrive circuitry?
