I think the first time I heard a 57 on snare, in person, because obviously we've heard the stories of a great record and the engineer saying 'oh, it's just a 57', only to try it ourselves and be like 'ok, can't be the same mic'. I even took pictures during setups that sounded good to mimic the mic placement and technique. To this day, I still don't use just a 57. I also tape a 451 to it for top and I use an sm7b on the bottom. This way, if the recording vibe ends up being something different in my head, I can mute a mic, adjust balance between the 3 mics....you just have more options. I'd rather have 3 signals with the ability to mute than to be fighting just the 57 with Eq to make it work. For guitars the same. I always put it up right along with my sm7b, i5, AEA R92, Heil Pr30. It's been a while since I've kept it's capture in the mix to be honest. However, sometimes even just a little of it in there gives me that extra 'thing' I wanted to hear in the performance. There's no one special mic for any situation IMO, some mics tend to work better for certain situations more reliably and the 57 is right there in the heap of useable mics on just about anything, but there's a reason why the term 'mic locker' exists.
