I upgraded to a Shure dual Mic kit and I'm finding that its so sensitive that I keep getting feedback. I need to be able to interact with my guests confidently knowing they can hear me clearly and that I won't have a problem with feedback. There's nothing worse than running out on the dance floor to bring attention to the Bride and pump up the crowd and it just going to shit.

What kind of mic do you use and are you happy with it?
