You could try Doug Maccormack in manchester new hampshire. He used to work for Daddys junky Music for 30 years as thier head tech. When Daddy's closed all the techs opened thier own shop called The Music Techs. He's done repaire for Aerosmith and a bunch of others I cant remember. www.dougmaccormack.com
I didn't have a good experience with Peter at Brokenneck. He did a refret on a custom shop fender and it was ugly. I still think of getting it redone by someone else.
If you don't mind going to Maine, I've heard great things about Steve Grenier at Main Street Music. He has done a bunch of Gibson neck repairs. Their number is 207-376-3376
