I'm trying to find out about availability of the windscreen for SM57 which has a rubber, friction-fit mounting ring, rather than the set-screw metal ring. I can't find that version on the website, and I suspect you may have discontinued it. But, if it is available, what is the part number?
The rubber friction version was unreliable and was discontinued. The current version uses the setscrew and is the A2WS-BLK or A2WS-GRA.
