Boss SD-1 Super Overdrive (Vintage) older ACA version made in Taiwan early 90's model. In very good condition.
Warm, Tube Drive Sounds
The SD-1 Super OverDrive pedal produces the warm, natural distortion of an overdriven tube amplifier while maintaining the subtle nuances of a player's picking technique. This is one of BOSS' more subtle and smooth overdrive pedals, perfect for blues and rock.
