The P was king into the mid 80s, when the post-jaco vibe got entrenched. I would say there was period in the mid to late 70s when it was hipper than hip to take a Jazz neck and stick it onto a P body. But the switch over to Jazz being preferred started in that late 70s period, where people were snapping up early Jazz basses. A good marker was that in 1983/84 at a vintage show in NYC you could have bought a stack knob refin for $1800, and a custom color 67 for $700. A pre-cbs P would have been in the grand area, and a 57/58 would be close to the $1500 mark or more. I have fairly accurate memories of that as I was buying at that show and came real close to buying the stack knob. Within a couple of years those prices were a sweet dream.
