To celebrate 40 years of continuous SD-1 production BOSS has created a limited edition version that’s available throughout 2021. This commemorative pedal features a black body with yellow lettering gold-capped knobs and a vintage silver thumbscrew for the battery compartment and comes in a box with a special 40th Anniversary logo. Legendary BOSS overdrive pedal with genre-defining sound and feel. Since its release in 1981 the workhorse SD-1 Super Overdrive has been the core gain pedal for generations of players across every musical genre. The SD-1 delivers rich smooth and highly musical overdrive tones that continue to inspire guitarists everywhere. Unique asymmetrical clipping circuit produces tube-like overdrive characteristics. Mild-to-moderate drive tones with focused midrange and tight low end. Ideal for use with clean and slightly driven amps. Also works great for bringing tightness and definition to high-gain amp tones. Stacks well with boost overdrive and distortion pedals.
