I do replace the inner foam pop filters in these mics as they are always shot. It's important to do that to any older 545, 545S or SM57. The new foam I install will last another 50 years. The 545S was a bit more expensive then the standard 545 version.

The Shure Beta 57 was a higher end dynamic super cardioid microphone in the Shure Brothers line up. This was the competition to any E.V RE15 or RE10. The sound quality and build is on par easily. The Shure Beta 57 has a beautiful warm tone with just the right amount of bass.

You can use the 57 or 421 for mounting. You can use the 421 mount clip or clip the 57 in as normal to a standard mic clamp. If you use the 57 mounting option then you can pivot the 42157 clip around 340 degrees and around 160 degrees in the other direction and then you also have your mic stand pivots.
