ProCo RAT Solo Distortion
100% analog signal path Heavy-duty, industrial footswitches, knobs, and jacks On/Off LED indicator Sloped face for easy stomping Glow in the dark graphics DC jack (RPS-1 power supply sold separately) Military-spec glass-epoxy circuit board "No tools required" battery compartment (9 volts not included) The solo uses three pairs of carefully matched (or should we say, carefully mismatched) clipping diodes to produce asymmetrical clipping. The three pairs are accessible via the “hot, melt, burn” slider switch. This has the effect of making the SOLO clip very much like a tube amp going into natural power-tube distortion. Pro Co Sound also makes several other highly regarded effects including the popular RAT2, Turbo RAT, You Dirty RAT, and Deucetone. Each effect has its own unique tone structure.
