It's the 2x12 combo version. Wow, this thing sounds like a really great Marshall! I'm trying to learn how to dial in my tone with it right now. It's a much brighter amp than my Lone Star, so I have to really turn down the presence and treble. I guess the brightness goes with the Marshall territory. I remember playing a Marshall Silver Jubilee and thinking how bright it was. Any other Ace owners find the amp really bright at first?
