Hey guys, Sorry if this has already been asked, but I didn't see it. I've narrowed my search down to one of these for my new (used) amp, and I've got a line on a used combo version of both for about $750 each. Any pros or cons of one or the other? Is the EF86 channel as must have? I've also read that the AC15HW1's are made better than the Heritage series. Any truth to that? Reliability is an issue since I'll be gigging with it. I'd appreciate any and all comments, because if I don't pull the trigger soon they'll probably both be gone... I've also thought a lot about the boutique market, but even at $750, I am maxed out budget-wise. Plus I don't think I would ever want to bring a $2000 amp into some of the clubs I play at! Thanks!
