1987 Proco Rat

ProCo RAT (1987) – Vintage Distortion Legend

The 1987 ProCo RAT is a true vintage classic — one of the most sought-after distortion pedals ever made. Built in the USA during the golden era of ProCo, this version of the RAT features the legendary **LM308N op-amp** and original through-hole circuitry, delivering the raw, gritty tone that defined alternative rock, punk, and grunge.

With its signature three-knob layout—Distortion, Filter, and Volume—the 1987 RAT offers everything from gritty overdrive and tight distortion to fuzz-like saturation. The unique Filter control cuts treble frequencies as you turn it clockwise, letting you go from searing leads to thick, wooly rhythm tones with ease.

This particular year is prized for its smooth gain structure, dynamic response, and massive midrange punch. Whether used as a primary dirt box or stacked with other drives, the 1987 RAT remains a go-to for guitarists chasing authentic, vintage distortion tone.
