I have a Music Man Freltess Bongo 5 string, lineless, with dots on the side. I know these dots line up exactly where the fret would be, and they are accurate up to the 9. after, they're off, in increasingly larger increments. I know the whole point of a fretless is to use your ear, which I do, I rarely look at the dots, however, when I play the upper register, it's nice to have a reference point, especially when the notes aren't where I think they should be. Any advice on how to make the notes closer to the actuall dot that they should line up to, or something else to help? Thanks!
