If I show up to an "outdoor festival" (when I hear festival I'm assuming one to two thousand people) and there is a "combo" of any sort waiting for me on the stage there you're not going to be able to hear the bands over my constant complaining and whining.
Best outdoor backline I've gotten in the last few years was a GK 1001RB and two of GK's lower-end 4x10 cabs. That was a damn cheap rig and I was running it "barely on" and it was more than loud enough. I appreciated it and let everyone know. Could I have used a combo? Yeah, because they had more than enough FOH and stage monitors, but frankly under circumstances like that I'd rather just have a direct line and get the combo off the stage so I don't look like I'm playing with a junior high band.
OP, I do agree with your stance on not using your own rig. I wouldn't either. That's never gone well for me and I won't do it again.
