Well, probably more than a tweak but hey.
My LP's intonation is a bit adrift in that all the strings are in tune, both open and at the 12th fret, but sharp on every other fret in between, and iffy above the 12th. The high strings are worse than the lower ones, but the pattern is consistent.
I'd like to try and sort this out myself but am not really sure where to start. Maybe I shoud just get in the car and go to Croydon....
