Guitar distortion effect pedal. This is the ultimate Swiss army knife for the analog guitarist. Consisting of two independent RAT units, each Deucetone channel can be used separately, in stereo, or cascaded together for the most insane distortion on earth. As if that weren't enough, each channel is switchable between three RAT settings. Channel A features the Vintage RAT, Turbo RAT, and Dirty RAT, while Channel B gives you the choice of Vintage RAT, Turbo RAT, or Clean RAT tones. The Clean RAT is a clean boost, a tone only available in the Deucetone RAT. That's like having six RAT pedals in one unit. Used separately or cascaded, you have fifteen RAT tones at your feet.
