collapse expand iconDescription

The ProCo FATRAT uses the highly acclaimed '85 Whiteface Reissue RAT as a platform, added a bass enhancement circuit, brand-new switchable clipping section and a whole lot more.

Clipping Section
The FATRAT is switchable between silicon clipping, as in the classic RAT, and a MOSFET/germanium clipping section, which is entirely new to the RAT line. The MOSFET clipping section gives you subtle scoop and smoothing in the upper mids throughout the entire gain range of the pedal, and makes the pedal sound more amp-like and natural.

Socketed Opamp
The pedal ships with the current stock chip (OP07DP). However, changing over to the mythical LM308, or other compatible chips, in the FATRAT will be a quick and simple mod that you can do solder-free.

Large, CTS Pots
They give you a smooth, even sweep throughout the range of the Distortion, Filter and Volume controls, allowing you easy access to the myriad of sweet spots in the tone machine.

Fat Switch
Provides a significant bass boost and simultaneous high cut—this makes the FATRAT more suitable for bass guitar, lower tunings, as well as fattening up and smoothing low-gain settings, making this a good candidate for overdrive use.

9-18V Operation
Increased headroom and fidelity with 18V operation and less “sagging” as compared to older RATs.

    This may be the only distortion pedal you'll ever need for metal. Plus it's a hand build from the USA!

    I love the Fat Rat. It's my favorite Rat next to the JHS Rat Pack, the reason is that the JHS Rat Pack doesn't cover the Fat Rat version at all. The Fat Rat circuit is heavily modified compared to the Rat Pack. I like it because it just sounds good. I use it in my doom tone and 80s metal. You also pull some nice thrash tone by adding an Eq pedal and I cut the mids.

    Been playing for 25+ years. I play anything from funk to metal. This pedal is sick as it gets. Pulling them other dirts off my pedal board. Huge thick sounds. Killer clean boost on a dirt channel for metal, tons of sustain and saturation but never looses control. No need to blow more $$$ on a JHS modded as this thing is unbelievable. Buy and u will be happy 😃
