Abstract: A guitar neck incorporating a mechanism for adjusting the degree of straightness of the neck's elongated body is provided herein. The mechanism incorporates a lever and tension-compression system to perform the neck adjustment. The lever and tension-compression system includes a platform and a driver connected pivotally to each other in end-to-end relationship. The platform acts as a lever, and the driver creates tension and actuates the lever. The platform and driver are mounted longitudinally of the neck in a groove (slot or passage), the upper and lower wall of which are adjacent to the platform. Pivot points are provided, preferably on the upper and lower walls of the groove, and cooperate with the platform in achieving the proper lever action.

Abstract: An improved neck for a guitar which is comprised of a elongated body, an elongated fingerboard, and an elongated strip. The fingerboard is mounted longitudinally of the body on the upper side of the body. The strip is mounted in the neck longitudinally of the body and fingerboard and near the junction between the body and fingerboard and being substantially parallel to the junction. The strip has a modulus of elasticity greater than the body and fingerboard. The strip can have a domed upper surface and a flat bottom surface and may be adhesively secured to, or molded, to the fingerboard in a wide shallow groove formed in the bottom of the fingerboard. The strip and fingerboard may be laminated to the top surface of the neck body. The neck body may have a truss rod or lever system therein.
