AT831b outstanding for autoharp

I've been using the AT831b in performance settings for over a year, and I've been thoroughly impressed with it. Autoharps are notoriously hard to mic, but this little dandy does an outstanding job capturing subtleties of sound normally lost when mic'ing with more traditional methods. I wear the AT831b in my clothing, behind the autoharp, and when combined with a good dynamic mic out in front of the instrument I'm able to produce a sound quality for the audience that is almost identical to what I hear myself. The sound quality is superb -- very natural -- and I've not had any problems with extraneous noise. Feedback issues were minimal. The AT831b is a permanent part of my gear, and I never leave home without this little gem.
