. . . Is the P pup in the PJ5 in the same place as a regular Pbass? That may really sway my decision.
I'm not exactly sure why you are asking, but if your concern is whether or not the PJ5 can closely emmulate the "old-school" P-Bass tone, then have no worries. It absolutely can.
The NYC PJ that I had copped a KILLER P-bass vibe by panning to the front PU and popping out the passive switch. Of course, it did much more than that as well.
The "out for delivery" bass I noted is an Alder/Morado PJ5 (Metro). I expect it to be of the same ilk, but there are some variances that ought to play into the equation. The NYC was a reversed P. The NYC was ash/maple.
But, I still expect a similar experience.

Congrats!!!
