I spent another hour or so with MIII v.1 last night. I was able to get some dirt that I liked. It helped to adjust the modeled cabinets along with sag & bias. There are some fat creamy tones in there. I'm liking the '57 Deluxe and the 65 DR the best. The 57 Deluxe can get a fat almost fuzz tone when you turn the gain up. I also messed with the built in fuzz box and thought the sounds where pretty darn good. I really want to give this a run in a band rehearsal. I know one thing for sure. This amp is really fun! For practice and playing it at home I love it. We'll see if it can do what I want/need with a band.
