I have 3 Audio Technica Pro37r small diaphram condenser mics for sale (I have 5 but am keeping 2). Studio use only, in good cosmetic and excellent working condition. $ 90.00 each, will sell separately. Would be willing to take some Shure SM57's on partial trade, provided they are in same condition (working and cosmetic). I also have 3 Shure A53M "donut" shock mounts for these, $20.00 each. Sorry, don't have original boxes. Can provide pictures if required, and I'm on the good guys list. Prices above do not include shipping. Thanks, BW
