Not that I know of but at rib fest on friday it must have been awfully humid. I had the screens and rats on and there definitely wasn't any direct rain but 20 minutes or so into the set I got that 'wind-type noise' that I guess water around the capsule makes. Didn't really realize until yesterday when it was really bad. Levels were off like crazy for Jackass flats (though the sound guy had a bizarre mix going). Switched the mics from right to left to see if it wasn't a cable or something but the same mic was still having serious level issues. It's channel on the UA5 was at max gain an wasn't even peaking at half the 120 screen, and I dialed back the other mic gain to 10 or 11 oclock to try and have roughly equal levels, though the good mic was still peaking a good deal higher.
I was too tired to remember last night, but after tracking out Jackass Flats this morning took them out and after taking off one of the caps there was definite moisture under the cap and on the connecter to the body. I've left the cap and body out on a paper towel drying all day, hopefully it doesn't have any significant damage.
