If my BE100 didn't have such a lackluster clean(not bright enough when presence set for the gain channels), yeah I'd be using one amp.....I have the most up to date with the orange board(2014) model, sounds GREAT...I hear the new Buxom Betty clean is the shit, if it's as good as claimed, yeah I probably could get all I need out of one amp and be happy. Until I get the guts up to ship my amp to Dave....it's looking more and more like a JC120 is in my future.
I like the idea of being finished and finding the sound I want(I'm there for gain/fx...cleans are actually being more difficult for the sound I want), more concentrating on playing/making music. Nothing against folks who like lots of amps, more power to ya(good for the companies that make the amps we love too)!
