I have had this amp for about a year now after I bought it off of Craig's list. It has taken me a while to get the hang of it, but I think I finally found an overdrive tone that I have been searching for. On the Blues Channel, if I dime the gain, it produces one of the best touch sensitive screaming lead tones I ever heard with my strat. This is counter-intuitive for me because I typically keep the gain low on my amps and crank the master volume to get more of a power tube distortion and avoid fizz. I think this amp was made to have the gain cranked. There is no harshness or annoying fizz and the sound is still touch sensitive and dynamic. I should mention that I recently changed the speaker to a Celestion Vintage 10, which I think is a huge improvement on the overdrive tones. The jury is still out on whether the speaker is an improvement on the clean tones, but in fairness it is not even broken in yet. I may finally be able to ditch my overdrive pedals!
