Yeah, I got some good info. I believe the mic is similar to, if not the same as, the Nakamichi cm50... a "pinpoint omni" cap on a small body with the battery power at the phone plug end (which is missing in my mic...) Next step, figure out the best method of providing power, plug ends, etc... fun!!! The mics are pretty closely matched (0.6dB) and the frequency charts look pretty much identical and I can't wait to try them out!!! I'll post some info when I learn more for the rest of us DIYers out there!!!
