I have an old Shure Unidyne III SM57 mic that I bought way back in the 1970s. It is built like a tank and still works. Here is an excerpt from an article I found:


"The Unidynes are great mics in their own right. According to an old friend of mine who visited the Shure factory back in the 70's, he was told this:
That the SM57 and the Unidyne III used the same cartridge, but that the 57 got the ones that passed all of the top QC tests. The Unidynes got the "2nd tier" QC cartridges. This, along with slight design differences in the "port" area of the mic's body, rendered a slightly different voicing to the Unidynes. I , along with many others, have a fondness for this slight variation. Good Unidynes (they tended to be a bit less consistent) are coveted for guitar ams, snare, and some vocals. If you find a good one, hang onto it!"


I got banned from Weight Watchers for dropping a bag of M&Ms on the floor.
It was the best game of Hungry Hippos I've ever seen!
