How big "traditional" cabs cab the Accugroove tri 210 challenge? What cabs have you retired after getting a tri 210? Can a tri210 really challenge a traditional 410 or 212 like Trace Elliot, Ampeg or Aguilar etc? I need to know because if I drop my money on one I wont be able to get a second cab in a long while. Also is it a must to have a really big poweramp for this cab? I have a Gibson GB440 on its way (same as Thunderfunk). Thanks!
