Pro Co Fat Rat

Versatile Clipping Section: The RAT Distortion pedal is legendary for its versatility, and this new version takes it up a notch. It features a switchable clipping section, allowing you to choose between classic silicon clipping, akin to the iconic RAT sound, and a mosfet/germanium clipping section, a brand-new addition to the RAT lineup. The mosfet clipping brings subtle midrange sculpting and smoothing across the entire gain spectrum, delivering an amp-like and natural tone that's sure to elevate your playing.

Customizable Chip: The RAT Distortion pedal comes with the stock OP07DP chip, but the pedal is designed with a socketed opamp, making chip swaps a breeze without any soldering. Experiment with the revered LM308 or other compatible chips to fine-tune your tone to perfection.

Enhanced Control: The pedal boasts large CTS pots for Distortion, Filter, and Volume controls, providing a smooth and even sweep throughout their ranges. This feature lets you easily explore the pedal's multitude of sweet spots, dialing in your ideal tone effortlessly.

  • 9 – 18V Operation: Offers increased headroom and fidelity compared to older RAT models
  • 100% Analog Signal Path: Preserves the integrity of your guitar's tone
  • Classic Steel Enclosure: Virtually indestructible for years of reliable performance
  • Industrial-Grade Components: Built with heavy-duty footswitches, knobs, and jacks
  • On/Off LED Indicator: Clearly indicates when the pedal is active
  • Military-Spec Circuit Board: Ensures durability and consistent performance
  • Battery Compartment: Easily accessible with no tools required (battery not included)
  • Five-Year Limited Warranty: Provides peace of mind for your investment
