Low Volume Output, what could it be? I had 2 these microphones in storage for at least 7 years. When I pulled them out of storage recently and tested them, one of the microphones have an extremely low volume output (and has a weird tinny phasey sound on vocals) while the other is normal and hot. What could be causing a low volume output? I called up AKG and they said if I sent it in for repair it could cost anywhere from $150-$500. Which is basically how much the microphone is worth. Any help to point me in the right direction or if anyone has any audio guys to recommend in LA or NYC.
