Boss OS-2 Overdrive and Distortion Pedal The OS-2 gives you a choice of overdrive or distortion or lets you combine both - all in a single compact pedal. This integration gives you more options than using serially connected units, and provides hard distortion that maintains the subtle nuances of single-coil guitar pickups.
