Boss 40th Anniversary Limited Edition Super Overdrive Pedal, SD-1

The Boss 40th Anniversary Limited Edition SD-1 Super Overdrive Pedal celebrates the legacy of one of the most innovative overdrive pedals ever. Sporting a sleek black colour scheme, this pedal's new look provides a unique aesthetic for this iconic circuit. The recognisable yellow/black colour combo has simply been reversed for this limited edition version. The SD-1's legendary status is more than warranted based on 40 years of peerless performance, this pedal is the perfect way to honour its heritage.


Easily one of the most unique overdrive pedals on the market right now thanks to one clever feature- asymmetric clipping. Most overdrive pedals clip symmetrically giving a slightly thinner sound, that's because asymmetrical clipping creates more harmonic overtones. This gives a richer, thicker sound, overall. This helps create the iconic driven tones the SD-1 is known for, and now with new dark visuals, you can celebrate its anniversary in style.
