What is it?
Way, way back, just before the dawn of the Eighties and way before the myriad of distortion pedals we now have the luxury of choosing from, you’d find that distortion — not fuzz or overdrive — as a stompbox was rather scarce. Maybe you had an early “Made-in-Japan” Boss DS-1, or rocked the MXR Distortion+ just like Randy Rhoads and others did, or possibly channeled David Gilmour’s sustained sizzle with an EHX Big Muff Pi. But the ProCo RAT, another soon-to-be-classic, was still an unknown pedal in its nascency.
