Slightly OTI bought a SM58 replacement screen to try on one of my Beta 57a mics. At around two inches away, I don't hear any *big* difference. Maybe, it sounds (ever so slightly) smoother with the 58 screen on it. The mic is a bit louder with the Beta 57a screen, because of the shape of the screen putting you closer to the element. I honestly didn't notice *much* of a change due to the proximity effect. It sounds good either way. I would use it, either way, for vocals. The biggest plus I see to having the 58 screen on the Beta 57a is the foam windscreens will fit better. YMMV 8)~~*my testing was not extensive.
