I'm losing the love for my Bassman RI; it's flabby low end is beginning to drive me nuts. And it's hurting my back! I'd like to make a change to a single 12" combo; can anyone recommend one that: Is loud enough for a four-piece pop band, Gets a GREAT "just breaking up" sound, Holds a TIGHT low end, And doesn't cost an arm and a leg? Here are a few I've already tried and don't like: Peavey Classic 30 Marshall JTM 30 and 60 Ampeg Jets Fender Hot Rods I'd prefer a single channel amp over a channel switcher, and would be happy to have reverb, though it's not a deal breaker. Thanks for the help!
