I bought a used Shure Beta 58 off of craigslist some time ago. The damn thing just stopped working one day. I tried to see about fixing it, but it was a ding dong mystery and the insides of that thing do not reveal secrets easily. Plus, a bunch of it is just glued in. I finally read about sending it in to Shure for “repair,” where they charge you half the cost of a new mic and you get… a new mic, in the box. No warranty or receipt required.
I can reveal, friends, it is true. Shure has a great product replacement system and sent me a brand new Beta 58A in the box with all the peripherals. All I had to do was fill out a form and provide CC payment info. I also sent in a GLXD1 wireless transmitter that’d gone wonky which they fixed for free! Again, no warranty! They just did it!
D.I.Y. repair is great, but sometimes you gotta just let shit go that’s a) impossible b) not worth the time. You can find all the info you need on the Shure support / service & repair page… https://www.shure.com/americas/support/service-repair
