Thanks haha. I am actually using a power amp that I got off of ebay (150 watts each stereo) running into my 4 12 mesa cab. It sounds pretty good, but I haven't had too much time to mess around with it. I will get to spend some more time with it tomorrow and in the coming week, though as my band is auditioning drummers. I know that it is definitely loud enough, though. I do find, however, that running it straight into my studio monitors and using the cab sims, it sounds more natural running it though my cab. It isn't too big of a deal to me, though as I plan to run it through the FOH through output one using my power amp and cab as a monitor using my power amp and output 2 when playing live. The good thing is: I can put a global EQ on output two and try to get it sounding better. It's not that it sounds bad, it just sounds different than the tone I get recording. I will figure it out eventually, I guess. I will update you with the results I get soon. Thanks again. Oh, and I haven't played it through any powered speakers like the QSCs, just my studio monitors.
