USED PROCO RAT DISTORTION WITH KEELEY MOD
The ProCo Rat is a classic in the world of distortion pedals. The Keeley mod takes the stock reissue and makes it closer to the sound of an original with an two additional modes for more tonal options.
Switch to the right: classic Rat sound with increased bass response
Switch to the left: "Phat Rat" mode. Adds an additional diode to the circuit for a more "tube" tone. Increased output.
Switch in the center: "Mighty Mouse" mode. Higher volumer output. Takes a diode out of the circuit. More natural sounding overdrive. Enough volume to push an amp into natural overdrive.
Another mod is the addition of a standard 9v dc power plug as opposed to the Rat's stock headphone jack style plug.
