If, however, you want to try to play an unlined fretless and you fear that the lack of positional references will prevent you from doing what all the little Suzuki children do, could you not put something on the back of the neck here and there to give yourself the positional references you need?
Unlined boards for the most part will have side dots for position references. I can't say all because the Takamine B10 has none. Just a whole lot of empty.
