The (D)Evolution of Pickups

[EVOLVEBASS]

I see many posts arguing whether older Warwicks are better than new because of pre-production quality, or wenge necks over ovangkol, or the brass nut, etc. I'm curious if there's been any notable changes to the pickups?

As a side topic, is anyone installing vintage pickups on newer Warwicks or other basses? I know that vintage Jazz bass pickups are very popular...
