Two innovations illustrated above.
Anodized aircraft grade aluminum or carbon fiber Exoskeleton™ extended range neck structure is incredibly lightweight, thin, stiff, stable, and resonant. Can be combined with a wood fretboard, as shown, for organic tone. Hickory and maple remain my two favorite fretboard materials, both North American species.
Patented Trapezoid Neck Profile™ (in one embodiment, above).
This neck, as drawn to scale, is approximately one half the thickness of a conventional neck. P1 surface is maximized for thumb stability and leverage. Net result is deepest possible fretboard penetration, combined with near ergonomic invisibility.
Second innovation is an integrated capo system that is actually part of the neck structure. By means of simple and sturdy spring loading, a capo rotates instantly into position to securely fret desired strings. This design has tremendous potential for extended range instruments, with the capability to transform a baritone into a conventional guitar.
Animals As Leaders & TRAM
Multi-scale capable. Easily removed from the instrument for transport.
As depicted here, the capo is fretting two strings of an 8-string guitar. Alternate embodiments of the invention include capability of fretting any or all strings of the guitar. Adjustable configuration capo arms. Alternate embodiments of the invention include "T" shaped capo arms, wherein the capo shaft penetrates through the fretboard, even between strings. Multiple capos can be employed throughout the neck.
