Since the cat's officially out of the bag I can say something about it since I have Lisa's blessing to post a little bit.
Both that Super P pickup and a Super J pickup are going into my custom NYC. It is indeed P and reverse P, and with the the Super J in the same sized shell (with 60's, 70's and both pickup selections available) this will be a VERY flexible combination! When I asked Lisa about this concept while commissioning my NYC I was really scared that it wouldn't be possible, but Lisa and Roger were very excited about it and worked tirelessly with Nordstrand to make it happen. I'm positive that @deepestend and
@Sadowsky could give a much more detailed account of the pickup, but from my perspective and ears Lisa and Roger have done an incredible job working with Nordstrand to nail this concept out of the park (I got to play it briefly while on some fly dates and stopping by the shop while in town for our NYC show).
I definitely promise to post lots of photos when I get the bass, and a good drummer friend of mine and I are already preparing to create some studio videos demonstrating the different tones available from the Super P and Super J pickups. Man, I'm getting more excited by the minute for this bass and pickups!!!
