The Boss SD1 Super Overdrive Pedal delivers exciting overdrive without ruining your guitar tone. The SD1 has a tone control allowing boost or cut in the highs to produce more varied overdrives.

Debuting in 1981, the Boss SD-1 is the second longest running Boss pedal and a great affordable alternative to a Tube Screamer.

This Boss SD1 is in very good condition and is fully functional. There are few signs of cosmetic wear.
