Ok I have a slight problem. Both the guitarists in my band are going to be upgrading to full stacks. So this means I need to upgrade and I'm not sure exactly what I need to do. I was thinking about going the preamp/poweramp setup and getting one of those new Behringer power amps. I'd probably just use my B2R as a pre in the meantime or something. Would this be all? Or do I need to add another cab to my SVT610HLF? Any suggestions are much appreciated. Thanks.
