I bought a vintage Shure Unisphere I 565SD Made in the USA. It is the early version of the SM58, but has been made in cheaper versions since the 1960's. This is not a 60's version since it has a XLR end on it. The really old one had the 4 pin connector. However, the mic I have still says Shure Brothers, Make in USA and Model 565SD. I am thinking it is from about the 1970's, but I could use a little help. I have called Shure and they can't tell me anything other than what is new. Kind of disappointed in that one. I will post a pic or two as soon as I can.
Any help would be greatly appreciated
