Boss OS-2 Overdrive/Distortion in good working condition.
From Boss:
DISTORTION AND OVERDRIVE TOGETHER AT LAST!
The OS-2 gives players a choice of overdrive or distortion or lets them combine both--all in a single compact pedal. Its distortion maintains the subtle nuances of single-coil guitar pickups.
Flexible distortion pedal capable of producing blended overdrive/distortion sounds
Provides both "over-the-top" distortion sounds and less extreme overdrive tones for rhythm playing
Includes Level, Tone, Drive and Color controls for precise tonal shaping
