I need a loud setup in order to play The Rock and Roll (the kind with the Marshall half-stacks). I don't have the dough to buy a 300 watt tube amp. However, I do have access to two inexpensive 100 watt tube heads. Now if I were to split my signal and run these two amps in tandem (with two cabs) would it ever get "loud" enough? Or would it just sound like two not-very-loud-amps, and not make the impact I hoped it would? I've got a hunch that it's not going to cut the mustard, since neither cab will ever be truly "loud" and sound pressure levels are probably not cumulative. Help?
