Dirty Rat

General Description

The Dirty Rat has nine ProCo Rats, and historical variations, to create the iconic guitar tones of the 70s, 80s, and 90s. The variations add a modern Rat tone to the Stage Amps.


The JHS PackRat aims to solve the riddle, "How many rodents can you stuff into a single stomp box?" The answer is apparently nine, because that's how many rodent-style tones you can coax out of this distortion pedal.

Like the Muffuletta did for fuzzes and the Bonsai did for green overdrives, the PackRat supplies you with a myriad of Rattus norvegicus-style sonic textures.

This flexible stomp really burns, able to churn out mild overdrive, metallic grind, and cacophonous fuzz with equal aplomb, leaning on four decades of tried-and-true — and some quite rare — ratty tones. Best of all, the PackRat doesn't use digital modeling.

Rather, it boasts the exact same components as the source units.

So, when you select a mode with the PackRat's rotary control, your guitar signal actually passes through a replica of the original pedal's circuitry.

Just about every pedalboard has a large-mouse-like stomp box on it, but with the JHS PackRat, you can have all the rodents.
