I just got a Heil PR30. It sounds sooo much better than any of my SM57's. I suck at making clips but at least now I don't have that muffled effect. Really pleased with the pr30 so far guitar clips.
I have owned an e906, e609 (still own), multiple sm57's, md421... Not too many but the usual suspects. I did a video clip using the pr30 and an e609 and those worked pretty well together (Fluff recommended that combo). I use an Apogee duet and my mac for audio and video clips. My mac needs updated because it can be slow when working with video.
