Boss OS-2 Overdrive / Distortion Guitar Effect Pedal (OS2)

RM570.00

Two Iconic Tones, One Pedal — Combines BOSS’s classic overdrive and distortion circuits in a single compact stompbox, eliminating the need to carry two separate pedals.
The COLOR Knob — Blend Your Perfect Gain — A dedicated dial smoothly morphs between warm, tube-like overdrive and heavier, more aggressive distortion, unlocking tones neither circuit could produce alone.
Preserves Your Guitar’s Natural Character — Careful circuit design retains the subtle nuances of single-coil pickups, so your instrument’s true voice comes through even at higher gain settings.
From Blues Crunch to Modern Rock — The wide-ranging DRIVE and TONE controls take you from subtle rhythm breakup to searing, cutting lead tones, covering an unusually broad stylistic range for one pedal.
A Guitarist’s Long-Term Companion — Popular for its versatility since release, players often keep the OS-2 in their collection for years, finding new creative uses even after owning other drive pedals.

Boss OS-2 Overdrive / Distortion Guitar Pedal (OS2)

Two Colorful Drives, One Powerful Pedal

The OS-2 Overdrive/Distortion features a versatile hybrid design that combines independent overdrive and distortion circuits in a single compact pedal. Praised by everyone from professional players to beginners for decades, its specially tuned circuits can be used alone or blended in parallel to achieve distinctive combinations. The ultra-flexible OS-2 offers an ideal balance of sonic diversity and ease of use, allowing guitarists to dial in great tones for every style in seconds.

FEATURES

Discrete overdrive and distortion circuits in a hybrid compact pedal
Classic BOSS overdrive circuit delivers rich, singing midrange
Precision-tuned distortion circuit supplies tightness and punch
Color knob for selecting isolated overdrive or distortion sounds or blending the two circuits in parallel

Dual-Drive Design

The OS-2’s overdrive circuit is rooted in the timeless design of the OD-1, one of the first BOSS compact pedals introduced in 1977. Asymmetrical clipping mimics the natural overdrive behaviour of tube amps, creating plush, responsive midrange tones that are perfect for edge-of-breakup rhythms and expressive lead playing. Meanwhile, the OS-2’s finely tuned distortion circuit uses hard clipping to produce sharp, fat tones for heavy chord work and searing solos.

One Knob, Many Colors

With its unique Color knob, OS-2 effortlessly transitions between overdrive, distortion, and distinctive combinations of the two types. Whether emulating the warm breakup of a pushed tube amp in electric blues, capturing the edgy crunch of classic rock, or nailing the intense saturation of grunge, this pedal excels at every turn. Enhance the clarity on the overdrive side with a touch of distortion. Or add midrange warmth to the distortion by mixing in some overdrive richness.

Versatility Meets Simplicity

Handling any type of pickup with ease, the OS-2’s simple controls deliver a surprising array of complex driven tones. Twisting the Color knob mixes the overdrive and distortion circuits in parallel, providing a smoother, more articulate result than you can get by stacking two pedals in series. Once you find your preferred blend, dial it in with familiar knobs that include Level, Tone, and wide-ranging Drive that goes from subtle to aggressive.
