A great neck pickup
I installed the Pearly Gates in the neck position of my PRS McCarty and am completely happy with it. It's clear (by humbucker standards), but with enough edge to keep things sufficiently rowdy.
When I use the p/u (in my normal medium-gain context) I hear the wood of my guitar like never before. And that's a good thing!
The SD jazz neck is a nice p/u and the Seth Lover neck is, to me, even better, but the Pearly Gates neck is better still and combines what I like about those other Duncan pickups into one classic-tone package.
My only minor complaint (the reason I didn't give it five stars): the split sound is, well...meh. But then again, I've never heard a split humbucker that really sounded satisfying and comparable to a real single coil.
