Interesting.... I have seen multiple ways for running live sound during a gig situation. I used to have a jsx head and full cabs.... toooooo much but fun as hell. then a boat load of boutique pedals. we toned down a bit and as I said before, plugged direct into the bose system. good but not great. so this time I am using my xxx single speaker combo amp with the 11r into the fx loop..... then downloaded a bunch of presets from the forum... I am not sure my overall sound for all songs has ever been any better than what we have now. It appears that the 11r has complete control. the amp itself adds nothing; vol, eq etc... the only thing on the amp that works is the boost which I like because it is variable and I can preset it. I would have thought the amp controls would have added something but , big fat nothing. thats ok for me as I only have one thing to look at on my system... the 11r.
