Abstract
An adjustable musical instrument neck stiffener includes a beam fabricated by embedding uni-directional material only at the upper portion of the beam, and constrained by braid or bias weave material. In a preferred embodiment, the uni-directional layers are preferably made from carbon fiber tow, cloth, or pultruded carbon fiber and the braid or bias weave material is made of carbon fibers. To reduce weight, the middle section of the beam is preferably hollow. A threaded rod and threaded sleeve provide a way to adjust the neck stiffener beam curvature so that it is straight while under string tension.
