The integral Rails are .060" high off the
deck and are exceptionally smooth to the fingers
for trills and slides. Their tips are
collectively machine cut to form an evenly planed
playing surface, then a subtle depression of
gradated relief is cut into this flat plane
of Rail tips at the low pitched half of the
fretboard, dipping deeper under the lowest bass
strings. This mechanized fret "dressing"
operation accommodates all familiar Stick type
tunings with no further fret work needed, just
the hard anodizing process to provide an oxide
surface extremely resistant to wear.
Colored hard-anodized coatings
The beams have a transverse pattern of finely cut lines running from nut to bridge. This machine cut surface texture has a slight glow in the way it diffuses light, contrasting nicely with the darker Rails and affording a better view of the frets under various lighting conditions. The surface pattern looks a lot like thin round wound guitar strings running across the board at right angles to the real strings. The anodized color is uniform over all surfaces of the neck beam, but the textured fingerboard surface makes the Rails stand out.Another option is a very hard metal-plasma coating with a brushed texture between the frets to diffuse the reflected light.
