hi, i was wondering if anyone had any mic recomendations or techniques for capturing low end vocals. i sing for a metalcore band and my usual mic setup is a 57 up close and a blue baby bottle a little further back, i mainly use the 57 but use the blue to take a bit of the edge off 57, but when i use this same setup for really low vocals (deathmetal type stuff) i lose a ton of definition and presence and lose it in the mix. any ideas?
