Can I use the XLR Out on my 200watt Traynor SB112 and run it in to the input of a second SB 112 to get more volume? Or would I be better off with either the bigger SB 115? Or just get a more powerful rig? Just trying to figure out the most economical way to get enough volume for bar gigs and corporate events. I just can't afford to spend $1000+ to do it the right way!!
