'railboard' fingerboard with integrated frets for stringed musical instruments

Abstract

For a stringed musical instrument of a type that includes guitars, electric bass guitars, and two-handed tapping instruments including the Chapman Stick ®, in departure from conventional frets inserted individually into slots or channels in a wooden fretboard/neck, a Railboard (TM) is made with frets that are precision-machined under CNC (computer numeric control) integral with the fretboard from a single block of rigid material such as aluminum. Optionally the instrument neck, whether body-attached or of through-neck construction, may also be integrated into the Railboard along with the fretted fingerboard. The fret-tips are initially machined with a sharp apex, then machine-dressed to form narrow flat fret-tip plateaus all aligned in a common plane, then selected frets are further precision machine-dressed to provide 'relief' in a lower-pitched region of the fretboard for optimal 'low action' playing characteristics, thus producing instruments of uniform quality in a cost-effective manner.
