I have used both a 57 combined with a Shure SM7, blended. The 57 usually is blended up , but not all the way, to give it that mid range and high end stuff, and the SM7 more fullness and body. on my EVH 5153 profile, I used a 57 combined with a Fathead II with lundhal transformers, blended the 57 up to taste to get some of the rasp and grind. I don't like the 57 by itself usually unless its placed really well, but I like it in conjunction with another mic
