I hope this is the right place to ask, but have any of you worked with non-standard fretboard layouts? There are of course many many many kinds. JI, equal temperaments other than 12-tone, historical well temperaments, etc, etc. I recently stumbled upon this Turkish fellow's new movable fret system, which seems quite promising. I asked him if he does electric instruments and basses in particular and he says he's working on it. The prices he plans to charge aren't particularly reasonable considering he's never even built an electric instrument before. Anyone think they could do something similar?
