The foam from the inside of the ball turned to gum many years ago. I
scraped it out and have been using an external foam pop filter over the
outside. I recently discovered new replacement balls on Amazon for
cheap, so I did that. I just recently noticed that the foam disc on top
of the capsule had deteriorated, so I removed it. I probably won't
operate this mic without the ball filter, so I guess the diaphragm is
protected enough and I might as well leave it as is.

All of that stuff is available pretty cheaply from Shure, although their
shipping makes it expensive if you only buy one thing at a time. But as
I pointed out, if you replace all the foam completely on an SM-58, you
get a mike that sounds like a new SM-58. And that's not always what you
want.

Of course it is, when you want to use it as a 57 you simply unscrew the
ball. Then you put it back on again for next time you want it for
vocals. Alternatively if you have 57's, slip on a foam sleeve when you
want them for vocals. You never have to worry about having the wrong one
anyway IMO. What I don't need is a 58 with a metal screen and no foam
though. Looks silly on instruments, and no good for vocals.
