Need to replace that trashed out or disintegrated inner foam on your nice Shure microphone?
This is the brand new genuine Shure replacement part #36A678A.
It will fit the following Shure microphones, wired or wireless:
SM58, Beta58A, SM48, PG58
Not too complicated, just unscrew the grille, extract the old foam, and put in a nice, clean new one.
These do NOT fit the non-ball type microphones. (Beta87, SM87, SM86)
I have a separate listing for those.
