Hey guys. What do you guys who own really clean amps, like Fenders, use for distortion? What would be good to give a Twin Reverb RI some classic rock to hard rock type distortion? Does'nt need to be perfect just passable and decent sounding. I already have a TS9 for blusey stuff, Timmy on order, and I'm just looking for something to cover some ground with If I only have one amp available. Thanks!
