Somebody point me in the right direction for an extention cabinet for my 5:25 combo. I don't know anything about the Mesa compact cabs but am considering getting the 1x12 wide body but I don't know whether to get the closed or open back model? Any pros or cons to either one if I'm using it in tandem with the stock open back combo? Or while I'm on the subject is there a better cab you'd recommend? Thanks in advance.
