I can see and appreciate that side of things, but you'd be hard pressed to get that kind of figured top or top notch attention to detail like you would with a Spector or other high end 'Fender-esque' bass. (...unless it's a custom shop which would cost the same or more!)
Fender branded passive J's and P's, as well as a ton of clone style J's and P's at all price points, all have different tonal nuances to my ears. IMO, the construction material (i.e. body wood, fretboard, pickup, bridge, attention to detail etc) contributes to the sound of a passive instrument more vs an active.
growing up imitating Duck Dunn, James Jamerson and Bob Babbitt, I've always seen the P-bass to be the perfect vehicle for that old school passive thump!!
...having said all that, I bet the Aggie guts sound wicked in them!
