We developed the line-markers. They are installed at the bass side of the fingerboard. They lie over the fingerboard edge and become block markers
(former side dots) on the side of the board. The lines are more visible than the 6 mm dots that are usually installed in the middle of the fingerboard. All the line markers have different lengths. It gives you a better position orientation. If you prefer, we can supply the classic 6 mm dots + side dots on the Vintech series with 5А Smilefrets.
