OVERDRIVE

This vintage overdrive circuit, originally built in the early '70s, delivers singing sustain on leads and crisp, tight bass on chords. Turn the gain down to provide tons of clean boost for overdriving vintage tube and non-master volume amps. Medium gain settings add tube-like harmonics for fatness and warmth. Higher gain settings produce rich crunch tones. Cleans up nicely when you back down the guitar volume.
