When I got it I noticed that the strings were out of alignment with the neck- Usually an easy fix by loosening the neck bolts and realigning the neck.
The problem is that it won't stay in place and there's not really any room to maneuver in the neck pocket.
I did see that there was a lot of paint buildup in the pocket (pretty amateur refinish I think) so I sanded it out back to the wood, thinking that this would give me the wriggle room I needed..... nope!
The only thing I can think now is that the bridge has been installed wrong. It has been upgraded to a wilkinson trem and while there appears to be no evidence of any filling and re-drilling going on, I'm wondering if it's been placed wrong. There is a larger gap between the high e end of the bridge and the pickguard but.... the original pickguard was an 8 hole and a newer 11 hole one has been fitted... out of alignment i think so it's skewing my perception. I should probably add that it's pickups are HH configuration. the pickups are attached to the pickguard so I can't look at the pole pieces for alignment clues as if the pickguard is skewed then so are the pole pieces!
I have limited photos at the moment but feel free to request more specific photos if it will help with diagnostics!
Alignment at nut (apologies, I snapped the high E earlier)

Alignment at 12th fret. Notice how the strings don't line up with the fret inlays

Bridge/ pickup alignment (it's hard to see the gap either side of the bridge

This shows the dodgy pickguar mounting

If anyone has a nugget of information for me then I will forever be grateful!
