I'm actually testing it right now, and the tone is perfect, the only problem is I don't think I'll get enough volume, the volume on my RAT is at half and it only sounds as loud as if the amp was at 2 or 3 on the volume knob, but I guess if I were to crank it and the volume sweep is accurate then it would be as loud as the amp at 6 which is the average gig volume I use.
EDIT: Actually I can get more than enough volume (living in an on-campus apartment, gotta be mindful) out of the pedal straight into the power amp and best of all it eliminates the buzz that I've got going on in my pre-amp. However, definitely need an EQ pedal as it sounds a bit dull, but this renewed my faith in my amp as I started messing with the settings on my pedal and plugged back into the normal input and I got a better tone than that which I had.
