I have decided to make my guitar the shape of an anchor. Does anyone know of a company/shop that can do this from bottom-up? like a custom body, custom neck, headstock, pot placement, etc.?
for under a billion dollars? nope.
Might want to contact a luthier.
Not a billion, but I'd expect anywhere from 1000-2500, realistically that would probably be the price range for a job like this. The real cost would be in the manual labor, and that will all vary depending on the experience and cost of the luthier.
