While I like my 5-string Rob Allen MB-2f, in retrospect I think I should have bought a fretless. Can I have it de-fretted (by a local very skillful guitar builder) or would you all recommend selling it and getting a new fretless instead? Are there any significant differences between a fretted and fretless instrument (apart from nut/bridge/string height) that would make de-fretting a less than good idea? I have little (zero) hope of finding a Rob Allen locally, I would have to import a new one, so trading is not practical, and I doubt I can get a good (high enough) price for it here either. Any thoughts?
