Neo's are very bright, precise and very powerful. They wouldn't be a good match for the JB which is already bright. I'm not sure anyone has actually figured out how to design a pickup to leverage the strengths and remedy the weaknesses of Neo magnets? I have two sets of Neo pickups the XS62 and the HDN from Entwistel. While I like both of them, I doubt either was specifically designed around the Neo magnets, because you can find pickups from Calig with nearly identical specs that are built with ceramic magnets. Both the Entwistel's and Calig's are part of the same Chinese conglomerate which produces other lesser known pickups like Sky, GFS, Artec and Dragonfire.
A darker pickup like a Dimarzio Super Distortion or a Invader might work?
