I just meant that at least in my mind, the Jazz Neck Humbucker seems to have been created to give a brighter, clearer tone than other humbuckers that were available at the time: early 70's.
I always suspected that Seymour, being a Fender player at heart, was trying to come up with a humbucker design with more clarity and sparkle...like we get from the neck pickup on our Strats. For THAT tone, an SSL-1, Tex Hot, Antiquity II, or any great 6-6.5K Strat neck pickup would probably do the trick.
I've never heard a Strat pickup with the actual tone of a Jazz neck HB...tho the Little 59 neck might be closest.
