Just ordered this baby, can't wait. I have been playing through a Carvin MB10 with a 112AG extension. It has done me well, but the keyboard player on the other side of the stage was always saying I can't hear you. So for now I will be running it through the 112AG and and Delta 12 in a slot ported cab. My plans are to do a fearful 12/6 and 12sub in the future. I will be doing that a little at a time. I plan on getting the 3012LF first then a 3012HO and put them in the cabs till I can get the flat packs. Anyone play the BX1500 through a 12/6 12sub combo?
