Microphones as a whole don't like moisture. How wet are we talking here? Dynamics in general are the most resistant. But the brand and design of the mic has a lot to do with it too.
the mics i have are a rode nt-1a, 2 oktava mc012's, 2 shure sm 57's, and a akg d112
the effects of moisture on the rode was verrrrrry obviously, but im not sure about the others, because i dont use them as much. and theres not that much moisture...jus some here
