Both of these microphones have been tested and work great. Impedance (L,M,H) is selected with a screw setting on the front. The chrome on one mic is excellent and the other has very slight (under the surface) pitting. I would call it VGC. These use a 3 pin (amphenol?) connector which I don't have a male plug for but was able to test with alligator clips. The connector setscrew is missing on one of the mics. I'm selling these for my church as they've been sitting in a box for quite some time. Shipping will be a flat $10 USPS Priority. Auction is for both mics, one price. Thanks for looking!
