I noticed today that my neck pickup was higher (closer to the string) at the G string than at the E string. I don't remember it being like that before, so I lowered it and liked the sound better. I can't remember if the bass came like this when I bought it or not. Maybe the screws just loosened a little over time?
That got me to wondering...
1. Is there an accepted standard distance between strings and pickups for Fender Jazz basses or basses in general?
2. How high are your pickups (distance from pickup to string)?
3. Should the pickup height be constant across all strings?
I have pretty low action, about 5/64" on all strings (@ 12th fret, string depressed at first fret). Not sure if that matters or not. I'm still fairly new to the bass, and very new to the world of setup, so any and all info is welcome!

Thanks.
