Right now I'm playing either a 400RB-III or backline 600 into an Avatar B210 Delta and an SB112 neo. They make a nice little stack, but I blew the speaker on the 112. I'm trying to decide whether to replace the speaker for $95 (12LFA) to $170 (3012HO) or maybe just get a different cab, probably used. I have a rather large gift card for GC that I could use for an MBE 210 or 212 or 410, or maybe find a decent cab in store, used. Or maybe I could just sell off what I have and have a 15/6 or 12/6 built? I'll probably stick with GK heads for the long run, but maybe get an MB500 or repair a 700RB. I had been saving the GC card for a deal on an MB500. I'm kinda set on having 8 ohm cabs, so I can always run 2, but do you really need that option with a 15/6 (paired with avatar B210)? What suggestions can you give me? I need to do something in the next few weeks since we'll start gigging again in January.
