ProCo Big Box RAT V2 1981 - 1983

The ProCo The RAT pedal was first manufactured in 1978, and has since been used by countless artists for its simple yet unique distorted sound. It features an LM308 op-amp noted for its poor slew rate, which creates a more distorted tone despite the simple circuit's resemblance to other distortion and fuzz pedals. With three knobs for Distortion, Filter, and Volume, the RAT is the quintessential distortion pedal.
