PROCO™ RAT™ REPLICA COMPLETE KIT

A complete kit for the Rodent, our ProCo™ Rat™ replica and one of the most famous distortion sounds ever recorded.

About the effect

The Rat™ is a hard-clipping op-amp distortion that has been a pedalboard staple since the late 1970s, equally at home as a gritty overdrive or a full-on fuzz. Our version is called the Rodent, and Scott Swartz contributed to the project. The project page also links archived schematics for Rat™ Version A, Version B and Brad's Rat™ updates, if you like to compare. Curious how the op-amp choice affects the sound? Watch our video comparing the OP07 and LM308 ICs below.
