My baby is a Fender American Elite P bass, which does have a number of differences from a standard P configuration.
The neck is C-D composite and it feels amazing.
It has a 21st fret (most regular Ps have 20) and the lowest and highest possible notes are both E (assuming E standard tuning). The symmetry pleases me, and I actually use that super high E in a few songs whereas before I would have to do a half-step bend, which kinda sucked.
It has a massive 18V preamp, and active 3-band EQ.
It has an active/passive switch, so even if I'm playing active and my batteries crap the bed I can always switch back to passive and stay in the groove (though this is a non-issue for me since I always play passive).
It has a 4th gen noiseless Jazz pickup, and a knob to blend between the traditional P and the J.
It has a truss rod adjustment wheel at the heel, which I find to be much better for adjusting.

All of this being said, I don't even put batteries in it, the active/passive switch for me is just a glorified mute switch (since it mutes when switched to active and no batteries), I very rarely use the J pickup, so in my case it's really just a glorified standard P with a really nice neck and a bunch of things on it I don't really use. I still love it though.
