"question - should I try out a beta 57?"
I did. better top end that is true, better separation from hhat, more gain but I dont know...
I still prefer sm57...
but lately I also put a small dynamic (actually a broken lavalier mic) INTO a snare shell - MAXIMUM separation - great impact.
I filter out all low mids and bass from it and gate it. then add this with high end boost to 57 track and compress both...
works very well and still sounds like 57 on snare but with added hifreq control
beta 57 is strange mic. I dont use it much I admit.
(disclaimer : I work mostly alternative/heavy music so on jazz kits maybe this wont work at all... on some mellower jazzy projects I did I used LDCs on snare with some distance - lots of details and realism...)
