Hey guys...

Both are very good mics that anyone should be able to achieve good sound with. The SM57 is a classic and many classic and modern guitar tracks have been recorded with them. The Heil PR20 is a different sound and sounds more balanced to my ear. Fuller on the low end, easier on the brightness, but one drawback is that it seems a little busy in the mids. Little EQ to fix this, not a big deal.

Any suggestions on getting a super tight, heavy guitar sound (ie new deftones, tool, chevelle, etc.)? I have a semipro recording studio so I don't, by far, have all the best gear, but I'm sure it can make the guitars sound pretty good with what I have if I knew what I was doing. My problem has always been too much "shhhhh" and not enough balls/warmth/punch.
