Re: Unpotted Jazz neck?
kingrazor-
Your Guitar will sound magnificent!! Mine is just like yours. One potted, one unpotted. Same pickups.
Have no fear, I am about to mix an unpotted Seth bridge I ordered with an RCA5 magnet for my SG re-issue I have, and am going to put a Jazz neck in it as they will sound killer, I know this. My Jazz neck has always been my favorite neck humbucker. I say I CAN hear the diff between a covered and uncovered pickup. Some say they can't tell the difference. Well, when it comes to POTTED pickups, I CANNOT TELL THE DIFFERENCE!! And I am PICKY!! 
I ordered 2 Hybrids from the custom shop unpotted, they accidentally made one with wax potting. MJ, the Queen of the Custom shop called to see if I would try it. I always say yes to MJ. 
So I put one each in 2 of my HSS Strats, all other parts the same, and I admit I cannot tell the difference, potted, unpotted, no difference. I used to take these and my SG on stage when I play, I have that much confidence in how good they sound. My playing days are over, spinal disease, stenosis and age have this month finally taken their toll, but oddly, my desire for good gear and guitars and constantly changing pickups like I do is still there. 
A gear head at 65, with no gigs! I will miss the occasional attention, but hey, I had a good run!
