I realize that the 6 probably beats the 3 in every category (except weight?) but I'm having trouble deciding between the 6.0 12T and the 3.0 10T. I play with a jazz/funk/fusion quartet mostly and we tend to play a lot of outside gigs. I don't want to get the 3.0 and then end up having to upgrade later on, but I also don't want to pay for a whole lot of power that I'm not gonna use. So I guess my main question is, would a 3.0 be loud enough and could I get a decent sound from it if I have it turned all the way up?
