Boss SD-1-4A Super Overdrive 40th Anniversary Special Edition

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. Based around the revolutionary asymmetrical clipping circuit from the OD-1 Overdrive - one of the three original BOSS compact pedals from 1977 - the SD-1 delivers rich, smooth, and highly musical overdrive tones that continue to inspire guitarists everywhere.

To celebrate 40 years of continuous SD-1 production, BOSS has created a limited edition anniversary 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.

WAZA CRAFT : The Art of Superior Tone

Since the beginning, the engineers at BOSS have been committed to achieving the finest guitar tones using any technology necessary, from old-school analog circuits to high-tech DSP. Continuing this enthusiastic spirit, we are pleased to introduce the new Waza Craft series.

Being made in Japan, the Waza Craft series brings you exceptional tone and touch response through carefully-selected analog components, refined circuitry, and meticulous attention to detail.
