I try to find out how different Shure SM57s from different eras can be to each other and in general, how large the tolerances between SM57s are.
I take 13 Shure SM57s, starting with vintage made in the USA SM57 Unidyne IIIs, going over various different Mexican made models all the way to contemporary 57s that you can buy today.
Speacial thanks to @lordgraga for letting me borrow two of his mics for this. You're a stud, mate!
I’ve started a Patreon where you can download full IR packs for the speakers I demo:
