I have a carvin 810, almost new, used less than a handful of times, I don't know if I'll ever have a use for it. I was trying to trade it off for either two 410's or a 115 and a 410. Just to give myself more options. I was offered a GB 410 extended range cabinet for it. My only concern would be, theres no way I could afford another GB cabinet to go with it. Would I be able to play through the GB 410 and a carvin 410 with no trouble? or would that cause problems? Should I hang onto the 810? should I trade for the GB? Should I get the GB and use it by itself or try to trade it for a 115 and 410 of another brand?
