I have both a twin and an AC30, and I must say, I seldom use either. Being that I am not in a band and only play in my basement studio, I find that both require far far to much volume to break up and sound great. I simply cannot play at that volume to get the proper tone without the walls shaking, dog barking, and wife banging on the floor! Some pedals help, but I tend to just use a Blues Jr or one of my tube Marshall combos for around the house jamming. I might trade my AC30 for an AC15, but I put Celestion Century speakers in the AC30, so I will probably have to get quite a bit of cash for it. The AC15, I am told, has a similar problem but to a lesser degree. Oh well!
