I just wanna share my experience with the rest here at the forum.
I use a CREATE XT for my performances and rehearsal, and still I'm trying to get the most of it, due to it's not too user friendly... you know.
I always had the problem with the input level, getting a lot of bleeding from the other instruments with a beta 58, and tones of feedback, although I played a lot with position of the mic from the speakers.
Finally, I tried to put a Behringer Shark in front of the Create XT, for the antifeedback feature and a little bit of noise gate, and the result is that I need to raise less the input gain to get the same result, with no feedback and, of course, less bleeding into the mic.
Hope that helps to anyone else.
