Used Boss SD-1 Super Overdrive Guitar Effect Pedal With Box

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.

This pedal is in used condition (as it's been used so it's rather worn!) but in perfect working order.  It comes with the box as well.
