I have an old Fender Newporter on which I want to replace the neck. I don't see a lot of info about replacement bolt-on necks for Fender acoustic guitars. Fender says they don't offer them. I've checked out web pages for LMii, USA Custom Guitars, Allparts, and Warmoth, but didn't really see anythng about accoustic necks. I haven't actually spoken to any of them. Anyone know anything about a good custom source?
