Yes, the Duncan FAQ's are a goldmine: I dig them for 12 or 15 years... And I wish they were still referenced by a number, as it was the case in the past (it was easier IMHO to know the answer 390 as refering to the PAF than to "question" the data bank without knowing if an answer will come or not).
Now, FAQ's are useful but can't we consider that personal/empirical experience is even better? The Web is full of samples recorded with P.A.F.'s and of discussions about them and it's really a fantastic initiatic travel to collect all these info's, in order to understand why people say what they say... And even if P.A.F. are "old" pickups evoked in "old" threads, the amount of vulgarized knowledge available about them on the Net is now higher than ever.
Of course, t's even more interesting to play and compare old pickups (if not to dissect and/or repair them as I had to do a couple of times): if someone really wants to hear how P.A.F.'s sound, there's shops with vintage treasures - and musicians, too: I wish I was the owner of the vintage Ricky, Fender and Gibson that I refresh once a year for a friend of mine... IOW: nothing equals a direct personal contact with the sound of P.A.F.s.
Last but not least: I won't post here all the links that I've posted elsewhere as a moderator, but passing an hour to listen YT vids recorded with real P.A.F.'s should be enough to
hear what most P.A.F.'s have tonally in common beyond their obvious diversity.
FWIW (= my two cents).
