BOSS SD-1W Super Overdrive Waza Craft Pedal

The BOSS SD-1W Super Overdrive is a premium Waza Craft redesign of BOSS's legendary SD-1, passionately engineered by master craftsmen in Japan to deliver superior tone that honors the original's 40-year legacy while expanding its tonal capabilities. The Waza Craft line represents the pinnacle of BOSS design and craftsmanship—featuring all-discrete analog circuitry, carefully selected premium components, refined circuit topology, and meticulous attention to detail that elevates every aspect of the playing experience.

The SD-1W features dual sound modes accessible via a front-panel toggle switch. Standard mode preserves the classic SD-1 tone that players have trusted for decades, faithfully reproducing the warm asymmetrical clipping character and mid-focused overdrive of the original circuit. Custom mode expands beyond the classic design, widening the tonal range and gain structure for more versatility while retaining the organic, touch-sensitive feel that defines great overdrive pedals. In both modes, the SD-1W is highly responsive to picking dynamics and guitar volume changes.

Made in Japan with all-discrete analog components and a premium buffered bypass circuit, the SD-1W is the SD-1 for players who demand nothing less than the best. Whether used in Standard mode for classic tube-like warmth or in Custom mode for extended tonal exploration, the SD-1W rewards expressive playing and responds like a living, breathing extension of the instrument. It is backed by the BOSS five-year warranty.
