Boss SD-1 Super Overdrive Pedal

The essential overdrive for pros and beginners alike. The Boss SD-1 Super Overdrive Pedal has earned its legendary status based on 40 years of peerless performance. This is easily the most unique overdrive pedal 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. It's a design feature which is patented by Boss (Roland), meaning the SD-1 is the only overdrive pedal that can offer this incredible tonal secret.
