So, I'm thinking about how cool it would be to add a 410 to the amp lineup & start looking around for options.... There isn't a lot of options, eh? I thought it might be cool to find a 410 that had a convertible back, and the Egnater Renegade 410X came up in my search. Anyone got a clue why there aren't too many 410 guitar cabs on the used market? And what there are loads & loads of 412, 212, and 1x12 variations, but why not very many 4x10 cab variations?
