The Rat On Steroids

The iconic Rat has had an overhaul, and here at Sweetwater, we're very excited! Pro Co's new US-made Fat Rat distortion pedal gives you a choice between the original or a new MOSFET clipping circuit, which delivers a smoother upper midrange for a more amp-like tone - without losing that classic, inimitable Rat feel. Also onboard is selectable bass enhancement that increases your low end response - perfect for bassists and down-tuned guitarists. Fat Rat now runs on 9-18 volts, juicing your headroom and fidelity, and sports a socketed op-amp, which lets you easily change between popular chips for even more tonal dexterity.

Follow up Review......

This is a follow up to my original review, hopefully this information will be useful to anyone looking at this pedal. As much as I love the classic Rat tone, sometimes the mids feel a little too forward and the pedal feels a bit stiff. I recently switched the clipping switch from Stock to MOSFET and the difference has been substantial. The pedal is much more natural and responsive in MOSFET mode, and mids are slightly more relaxed. Medium gain tones are more convincing and the pedal just feels better to play. I am using this pedal with two LP's and a vintage Gretsch, all played through clean Fender amps. I set the Fat Rat up for a good medium gain tone, then boost it with a Mini Tube Screamer for leads and heavier sounds. Initially I preferred the Stock sound, which is based on the Whiteface Rat. After several more hours of playing I now prefer the MOSFET setting. Overall, I am still very happy with this pedal and continue to find good sounds in it. I am glad I purchased a real Rat and not a clone. I hope this information is helpful. Rock on!!

A Modern Classic

I purchased two Fat Rats from Sweetwater and I am extremely satisfied with them. One is on my board and the other serves as a backup. The stock chip sounds very good, but I did end up replacing the chips in both pedals with some old LM308N's. To my ears the 308's are slightly darker and smoother. This pedal replaced an OCD and a Crunch Box and works much better with my Fender amps. The different modes work very well and offer very usable tones, although I prefer the stock settings most of the time. The large case, vintage style knobs and silk screened logo remind me of the old Rats I used to own. Best thing is the tone, it sounds like my old Rats and has some added versatility as well. The socketed op-amp is a simple but brilliant idea, more manufacturers should do this. The pedal is built like a tank and everything is neatly wired and assembled. If you are a Rat fan or are looking for something different and more "old school" I highly suggest you consider the Fat Rat.
