i realize this is the solidbody part of the forum but if you all dont mind, i had a very similar problem with my epi acoustic, the headstock snapped almost completly off after a very bad plane ride. i pulled the crack open, gave it some carpenters glue, let it seep inside and used some fine rope to tie the headstock down to the endpin and let it sit for about a week. then i carefully remove the rope, restrung and tuned, waiting for the neck to snap in half, but it didnt, it still holds its tune extremely well and i havent had problems with it for a couple years now. i probly just got lucky but it wasnt worth the expence to take it to a pro. good luck some times good things just happen. my apologies for taking about acoustics in the solid body thred, thanks
