A fantastic vintage distortion pedal that really sounds phenomenal. This deluxe version has a tone control which was not available on their other distortion. The tone sweep is huge on this pedal which would lend itself to also being used as a bass distortion. Controls are Distortion, Tone, and Output. This pedal uses a TL074 opamp based circuit and runs on two 9 volt batteries or an optional 12v AC adapter.
