I have a Marshall 1960A 4x12 cab. with 4 G12-T75 speakers in it. I also just purchased a Peavey Triple XXX head. This thing sounds awsome. My question is......I was thinking about changeing the cab's setup like the new bogner uberschall cab with 2 vintage 30's and to T75's. My question is how would I connect the speakers up to the existing terminal so that plugged into one slot it's 16ohm, and plugged into the other slot it's 4ohm, and plugged into the 16ohm of two cabbinets 8ohms. How much would the sound differ and in what ways? I'm all about getting the best tone I can with the gear I've got. Any help or opinions would be greatly appreciated.
