Yeah all the hardware on that bass is Hipshot. That's their A-style Fender-mount aluminium bridge.
I think I have worked out why my neck pickup is tilting:
Even though the pickups are short leg the fact that the screws are the long leg length means that the screws are bottoming out against the bottom of the cavity as I wind the pickup down and the pickup tilts over as a result.
Steve didn't cut in the leg recesses when he routed the neck pickup cavity.
So I am thinking this can be fixed by cutting the excess off of the pickup height adjustment screws as they are way longer than needed.
