This is the most classic sounding of all RAT distortion pedals. Think '60s garage rock. Think early punk. Think about the bands that changed the sound of rock 'n' roll. The key to the You Dirty RAT tone is in its germanium clipping diodes. Any pedal aficionado will tell you that nothing compares to the warm tone that these sought after components provide. This pedal is the perfect middle ground between distortion and fuzz, combining the characteristic cutting RAT tone with the warmth of a classic fuzz-tone. The You Dirty RAT also provides 3 dB more compression than the original RAT. This not only provides more "tube amp warmth," but ads extra sustain. The You Dirty RAT features the legendary RAT Filter control. Turn it to the right to roll off brittle high-end frequencies. Having trouble cutting through the mix? Turn the Filter down and allow the natural brightness of your instrument to shine through. The Distortion and Volume controls dial in the perfect amount of gain while keeping the level consistent with your clean tone. While there's no mistaking the legendary RAT tone when the pedal is on, true-bypass switching ensures that when the pedal is off, there is no coloration of your sound. Pro Co Sound also makes several other highly regarded effects including the popular RAT2, Turbo RAT, Deucetone RAT, and SOLO. Each effect has its own unique tone structure.
