I get it. Some folks do feel that way. I've AB'd a 4 Pro and 7 Pro out of the same cab and there's something to the sound of amps with those bigass transformers, and a smattering of tubes doesn't hurt either. I still dig the lightweighters, though. To me, their differences are like the differences between a tube amp running dead clean and a tube amp being pushed slightly hard and getting into the sag without getting into full distortion. Of course, neither is an exact duplicate for those sounds, but that's how they break down to me. The 3 Pro is pretty adept at doing both, although I'd say it's closer to the 4 Pro in tone and feel than the 7 Pro. Used to have one...when micros first came out I swore I was done with trad SS amps, but I kind of wish I'd have kept the 3 Pro now.
