Certain basses have much rounder necks (radius) than others.
I have one bass that is noticeably rounder than my others.
A lot of pickups are flat across the surface. Yes, you get a bit of adjustment on height on some pickups (split style) but there are soapbars and humbuckers that are dead flat across with no individual polepiece height fix.
On a neck with a pronounced radius you will have different string height across some of these pickups.
The string height is adjusted for playability on the neck so you can't mess with it for the flat pickup.
Just something you have to live with?
