Re: Seth Neck VS. Other A2 Duncan Pickups
Seth neck is unpotted so that alone makes a big difference. There's a character to the Seths that isn't in the PGn or the A2Pn. Call it hollow, call it woody, call it open, whatever. It's something that you have to hear to understand.
The pearly gates set is my favorite potted humbucker (both neck and bridge). It's not for everybody, admittedly. But for the life of my I can't figure out why. If you have a tube amp that you can turn up all the way until the power tubes start clipping, the pearly gates is like this midrange fist of cutting guitar balls (in the bridge) and warm woman tone (in the neck). It's clear enough that despite being dark in the neck position you can still hear all the notes. It's seriously one of those sounds that makes the back of the hair on my neck stand up. I understand THAT others don't like it so much and I respect their opinion so understand that you may not like it because it's thin or has too much treble or something like that.
I've said it before in a different thread but you really have to treat the PGb like a tele bridge pickup... It's not like your standard humbucker where you don't have to worry about your dynamics or your phrasing (as much... Obviously there are humbuckers that are really sensitive to phrasing, like the seth lover for example, but a tele bridge pickup will jump all over you... and even if you are on top of your game the treble can still be too much for some.)
I love love love the seth lover neck though. The seths have this character you can't get from any of the other pickups you mentioned. It's awesome, and I've never met anybody who didn't like the seth lovers. So, I would try them out. If I were to make a comparison the seth lovers are like running your hands over a really nice piece of rosewood whereas the pearly gates are like finished maple. Brighter, but not necessarily more detailed... I don't know. I can almost guarantee you'll like the seth but I can't say the same about the PG set. If you do like the PG set though you'll absolutely love it. They're those kind of pickups.
