A bit off topic, but this thread brought up an issue I ran into.
I recently pulled out an old Shure 55 that our band used when I was playing in the late 60s and early 70s. Serial number was 5928V which means 28th week of 1959. Its got the three impedance switch, and luckily I still had the Amphenol tipped cable! Anyway, its been over 40 years since I fired it up, and decided to plug it in and see what it sounded like.
Much to my surprise, it did not fit on any of my current mic stands. It slid right over the threads with some room to spare. It didn't do that in 1970, as the drummer used it (securely) for a vocal mic on a boom. The calipers measured 11/16ID. Does anyone know if there was a change in thread size from the 50s to the current 5/8 27thread standard?
I also found an old high impedence Unidyne B 515A and an EV 1750 Electret condenser mic. I haven't plugged either of those up yet.
Now if I only had old Fuzz Face and Fender Blender! Alas, those appear to have walked away years ago.
