I do not like condenser mics for stage use, unless you've got a pro audio sound tech in front, operating the mix. I agree with Nicole, that they can be managed in live stage situations - but I think they are usually NOT managed! If you've got someone who really knows their stuff and will work with that mic/s - fine ... otherwsie, there are some pretty darn good dynamic mics available; they're cheaper, they hold up better, they don't require power, and they are much easier to work with.

There is one more disadvantage to using a condenser mic on-stage; even f you can control the feedback and get a good mix ... they do pick up much more of the unwanted stage noise. The ring of the room, crowd noise, movements on stage etc ... you'll be amplfying these as well.

Again, I'd say for live sound use, if you have a pro sound tech with you, go for it - condenser mics do offer some great sound - otherwise, good dynamic mics work pretty darn well, and help you avoid many headaches.
