Hey guys, My bass player and I are updating our rigs for playing shows this summer. Right now I am using an rg2228 tuned to drop A with a low E. My amp is an Axe Fx standard into a Mesa 2:90 into an Orange 212 open back. I haven't played in a band setting with this cab and 8 string yet. Will it be sufficient for playing shows? And will it be tight enough? How about if I made a panel to seal the back of it? Or will I have to upgrade to a 4x12? If it will work, my bass player can get his new Dingwall Combustion.
