Quickly becoming a legend known worldwide for it's AMAZING heavy metal style tube distortion. Brother to the SS-11 preamp, but the SS-20 was designed based on tigher, crunchier, more aggressive styles of guitar playing. Incredible Clean, Overdrive, Distortion, and Lead tones in a compact tube valve driven pedal. We are raising the bar and technology in modern day pedal design and offer affordable high end guitar tone pedals. This one is going to be finding its way onto lots of pedalboards! Our principle and motto for this device is it is the valve that sounds and sings, however, the transistors do their best to help it sound in all its beauty and originality. Next best option to buying an expensive amp head!
