Hello all,
I'm posting on behalf of a friend who owns an old Gordon smith GS1 (LP junior style)
Unfortunately it was dropped (from a strap I lent her :-S) and now there's a crack in the paint across point where neck meets headstock (in classic les paul style \/ ).

(this is an image of a more serious break to show the location)
The headstock is still attached but tuning stability has disappeared. Can anything be done about it?
How much would it cost to repair?
Many thanks!
PS feel free to move to tech if this is misplaced.
