Beyond repair? Won’t mention any names but a friend of mine managed to smash his vintage D28 - he’d ski’d to the local session with it in a gig bag on his back and fell over on the way home.

We recommended a (now retired) luthier to him who did his best to persuade him to put a new top on it but no, he wanted the old one repairing. I remember seeing the small pieces of Brazilian rosewood he used to patch the back where the neck block broke through! The job took ages, presumably cost him but, as far as I’m aware, he’s still playing it.

Nothing is beyond repair, at a cost, except possibly a piano.
