I'm going down to the cloud forests of Peru to record a bird nature doc and I'm a little worried about the moisture down there. The mic that I'm worried about is the Sennheiser MKH 70 with a zeppelin and fuzzy...my question is what's an easy way to make that mic more water resistant?? I've heard (though never tried) the condom method, just rolling a condom over it, are there other ways? How does a condom effect the sound? thanks so much for the help!!
