The Pro Co RAT is a classic distortion pedal renowned for its versatile, aggressive sound and distinctive midrange character. Introduced in the late 1970s, it features a simple three-knob layout, Distortion, Filter, and Volume, allowing for a wide range of tones from subtle overdrive to saturated fuzz. Its signature circuit, based on op-amp clipping, delivers a gritty, harmonically rich distortion favored by guitarists across genres, from rock and punk to metal and alternative. The RAT is celebrated for its rugged build quality and its ability to cut through mixes, making it a staple on pedalboards worldwide.
