Love your P bass!! Thanks for the compliment on my J. I don't think your crazy at all, I too think the Hacked up ones are fun to look at. They show all the love they have received. I paid $1,000 for it and it sounds better than any bass I've played.
That's a FANTASTIC price IMO, I actually got my 62 for $950 last spring...I still can't believe it.
Mine is a refin though (neck and body, but headstock has not been touched) and it also has a jazz PU added before I got it. The good news is the previous owner didn't add an extra control for the jazz PU (no extra holes in the pick guard), and it's wired V/V and hardwired to 100% full tone. I can't roll the tone back, but honestly, have never needed to. It's a beast with it's own character. And every time I pick it up, it reminds me of how incredible a pre-CBS bass can feel. Every other bass I own feels like a toy compared to this bass.
Here's an older pic...I put the original bridge back on since this was taken and but the BAII on my 75 P.
