Jay Turser - JTB-900 - Need some help with pickup replacements

I got this in 2000 and it never really sounded that good. Only pic I can find of it is on the wayback machine. (Electric Bass Guitars by Jay Turser, page 9, Music Industries On Line - The official Jay Turser Guitars and Basses Web site.)

Recently a supposed guitar tech was going to rewire the thing, but I had no clue he had relapsed into drugs.

I finally got it back and the pickups were toasted - screws were forced into it, some are missing and I just want to finally pull it all out and get some good pickups.

The bass is pretty gorgeous and light but it needs that P-J sound....

Been a bass player since 1993, but never got much into the tech until recently.

I would prefer passives.
