Sorry, but I am so tired of seeing this one. I fight a Twin in the rehearsal space all the time, and I just bought an AC30 with a MV and it's almost as touchy even with a gain / master setup. It's so hard to find the right pinprick on the dial between zero and too loud, and the amp just doesn't sound as good as it does on 3-4, and we both know it sounds its best even higher than that. If I turn my guitar volume down to 1 or 2, my boost and comp pedals work entirely differently and not well. One can play a huge amp quietly, it's just not that great an experience. Old school tube amps have a comfort zone they are designed for.
