i received a pair of c4s for christmas from my parents who bought them from sweetwater. i have used them about 3 times without changing the caps but the other day i changed the caps from the omnis to the cards and they when i tried to take the cards off the threading came off of the the mic body and is stuck on the cardioid cap. is there a quick fix for this or should i get ahold of sweetwater and tell them about it so i dont ruin anything? i have a show to tape in about 2 weeks and these are my only mics. thanks for any help!
