Hello --- inquiring the expertise of the luthiers here. Wondering how feasible it is to replace a 20 fret 34" scale with a 22 fret 34" scale fretboard? Would a luthier be able to do this if there is room on the bass? I am seeking a reasonably priced ES335 bod-type 4 string 34" scale w 22 frets. Closest thing I find is Gibson Memphis bass, but only has 20 frets. Looks like there is ample room for replacing w a longer fretboard or extending it.
