The OS-2 is a solid, reliable workhorse for adding some extra bite. It’s a great option for guitarists wanting a straightforward overdrive/distortion sound without a ton of fuss – perfect for rock, blues, and even some heavier styles needing a little extra edge. The compact size makes it ideal for smaller pedalboards too.
Product Description
Boss OS-2, Overdrive / Distortion Pedal
- The BOSS OS2 provides overdrive (tube-like
- harmonic distortion) and distortion (which is much more intense). With the colour control
- you can adjust sounds between these two extremes. The tone control can then be used to adjust the treble. A very versatile pedal!
- Overdrive and distortion can be mixed
- Level
- Tone
- Drive and Colour adjustable
- Battery and mains operation possible
- Very compact and robust design
- Well suited for beginners
PROS
- • Compact and durable build quality, typical of Boss’s rugged construction
- • Colour control offers a surprisingly wide range of overdrive tones
- • Effective for adding sustain and grit to clean or already distorted signals
- • Level control maintains output volume, useful for stacking in a chain
CONS
- • The tone control is fairly basic, lacking precise mid-frequency adjustment
- • High-gain settings can become muddy and lack clarity, especially with darker pickups
- • Limited versatility compared to multi-effect units or pedals with more complex controls

Frequently Asked Questions
