ABSTRACT:
A guitar fingerboard provided with modular fretboard construction for ease of fretboard replacement, superior fret anchoring bi-directional string bending, and a fretboard design with longitudinal facets cut on a latitudinal arc shape that undulates from fret land areas in high regions to low regions substantially midway between the fret spacing that generates a musical scale progression, for increased playing action. The modular feature is due to a dovetailed form constructed in the fretboard and the neck of the stringed instrument to allow easy and fast replacement of the fretboard. The geometric configuration of the base of the fret, anchors the fret into the fretboard giving it superior stability. The arc facets are formed in a transverse direction to the length of the fretboard and are undulated from high regions at the fret to low regions between the frets by means of a transverse arc form defining fingering regions. The frets are cut on a transverse arc that spans the apex land area of the undulating form, like the arc facets, so that when bending of the string and chords are desired, the strings can be bent in either direction across the arc facet in an unrestricted fashion. The increased action is due to the smooth arc facet form and non-protruding arc land at the apex of the fret.
