Would it be possible to flatten a 9.5 radius fretboard to 12"?

    I know that I would have to refret. I don't think that flattening it would hit the truss rod.

    Then again I might be wrong. Is this a stupid idea? Or would I be better off getting a new fretboard/neck?

    Possible, yes. Worth it? Up to you

    Not a big deal. Yes, obviously it would require a refret. The cost wouldn't be much more than the cost of the refret. Flattening the fingerboard from 9.5" to 12" radius would lower the center of the fingerboard about 0.050", so the neck would feel a little thinner, front to back. Any Luthier capable of doing a refret should be able to do that modification for you.

    The only potential problem is inlays. If they are made of thin material, they might have to be redone. Normal dots wouldn't be any problem.

    I went the opposite direction, but I was also defretting the bass; got a 10" sanding block to curve the fingerboard to my preference (I think it was 12" or 14" when I started). Worked fine.
