Running a line from a 50w rogue amp (line out) into a cab, my band plays hard rock/metal (not death metal or anything) but my amp is not loud enough because of the guitars (typical bass problem) overdrive helps but i need a cab for sure. What should i be getting ? I'll take any opinions into consideration, even if i need a bigger amp. My amp does have a line out like i said, to plug into PA System or Cab
