Description
The OS-2 solves the age-old pedalboard dilemma of choosing between overdrive and distortion by refusing to pick a side. Instead of a single gain circuit, Boss built two distinct voices into this compact housing and gave you a Color control to crossfade between them, opening up a range that runs from touch-sensitive rhythm crunch to saturated, cranked-amp lead tones.
What sets the OS-2 apart from straightforward distortion boxes is how it treats single-coil pickups. Rather than flattening their character under heavy gain, the circuit preserves the pick attack and string nuance that Strat and Tele players rely on, so the pedal stays articulate even when pushed hard. Stack the overdrive and distortion sides together and you get a thicker, layered saturation that’s harder to achieve with a single-mode pedal.
- Blendable overdrive and distortion voices via the Color knob
- Level, Tone, Drive, and Color controls for detailed tone shaping
- Covers everything from subtle rhythm breakup to full-tilt lead distortion
- Retains pickup nuance, especially with single-coils
- Runs on a 9V battery (included) or optional PSA-series adaptor, drawing 12mA
- Compact steel chassis: 73mm W x 129mm D x 59mm H, 400g

Place it early in your drive stack for a foundational gain platform, or use it as your sole grit pedal when you need both edge-of-breakup and heavy saturation from a single footswitch. Either way, the OS-2 earns its spot as one of the more versatile two-in-one gain pedals on any board.
