From that spot, the grill gives you the big, warm woof, and miking in a way that includes more than one cone really lets the tricone shimmer come through. I’ve used an SM57 there before and got good results, but the e604 is way smaller and lighter, so once it’s in place, it doesn’t budge while you play.
Tone-wise, it’s in the same ballpark as a 57, but the placement is easier to nail, and it’s less in the way visually. I grabbed mine for about $150, and after my last gig with it, I’m sold. See the pic for exactly how it’s mounted and where it’s pointing.
