When I was a senoir in High School, We had a catwalk above our stage to set-up lights and drop down over head mics etc and saw a buddy of mine drop a SM57 about 30ft and it lived without issue! He was so scared he was shaking because he thought it was going to be AFU, I was laughing like hell as he was kind of a know it all I had already tried to kill plenty of SM57's and SM58's as I had been in a band for 4 years by then. I still have two mics that I bought new in 1979 and they work great. I have a Kustom mic that was built in 1970 it works perfectly and is mint (it is really a Shure mic with Kustom labeling on it). I used it before I could get my hands on a SM57 and 58
