Re: Pro Co Rat
According to Pro Co's web site re: the Rat :
Full control of the sound is provided by distortion amount, filter, and volume controls. Tune in just the right amount of overdrive, get the presence you need without the tinny treble, and balance the volume for the perfect extra "kick" for lead breaks. Distortion, sustain, fuzz, or overdrive: the sound remains unmistakably yours--not fake or gimmicky.
