Re: Reparing a Shure SM58
If your talking about the coilwires on the diaphragm, you have to be very good at soldering with a variable temperature contolled soldering station, good magnifiers and pretty much one shot a doing it. You will have to carefully remove the varnish from the wires and bridge the broken gap with more of the same diameter wire. You are better off replacing the capsule. Hope this helps.

I'm assuming that you have tried the obvious stuff like using a different cable and a different amplifier?
The Shure beta 57a is a very robust and reliable dynamic microphone and there is very little to go wrong with it apart from
A wire broken off inside
A broken capsule - can be caused by dropping it
You can inspect for broken wires by very gently unscrewing the microphone head and peering inside - however the wiring is quite short so be careful not to pull any wires off in the process.
A broken capsule can be replaced - contact your local dealer for parts.
The SM58 is a very rugged and reliable microphone and there are not many things to go wrong with it.
Assuming that you have tried using a different cable / amplifier to issolat ethe problem to teh microphone itself the most likely things are.
A wire has come off inside - gently unscrew the top of the mic - lift it off carefully lift because the wires inside are quite short.
A broken capsule - this usually results from dropping the mic on hard surfaces. Replacement capsules can be bought quite cheaply.Just tak careful note of the wiring order before disconnecting the old one.
Check the continuity between pins 2 and 3 of the connector with an ohmmeter. If there is no continuity, the cartridge is bad and will have to be replaced. The fine voice coil wires get damaged and that is fatal for the cartridge.
Unfortunately the sm58 capsule is very hard to get apart without damaging the contact surface.
You would have to take the contact side apart 1rst bend all the little tabs away which hold the brass plated disk in place then its a matter of edging the disk out....CAREFULL any scratch is bad! Once you have the disk out you will need a 1/4" socket to remove the shaft bolt, unsolder the green and yellow wires taking note where they were soldered. Then the element can be pulled out. What to after that, I'll let that up to you. Be wary, you will void warranty.
Most likely cause is tiny copper windings from cartridge to the solder terminals has broken (dropped?). CAREFULLY check for a human hair sized wire leading from the cartridge to the solder terminals that may be broken. Soldering and general repair of these ultra fine wires should be performed by a steady hand and light touch. Once repaired, the capsule (element) itself should read 10-20 ohms when disconnected from the green / yellow wiring....Glen
