Does anyone here use 2 heads through the D-13 2x12 cab using one head per speaker? I'm curious as to how it might sound that way. I'm thinking about using my FTR with one speaker and my 10/20 through the other. My other option is to just get a 1x12 cab for the 10/20 and use both speaker cabs. My D-13 2x12 cab is currently unloaded, so I'm not sure how Fred wires them, up. I know how to wire it if I use the speakers seperately for each head, but not if I use the cab alone with the FTR. Also, is the 1x12 cab the same height and depth of the 2x12?
