Abstract: A self-aligning neck joint for releasably securing the neck of an electric guitar to the guitar body and maintaining the neck in fixed proper alignment with the body. The neck joint includes a first bracket secured in a channel in the underside of the upper end of the neck and a second bracket secured in a neck pocket in the guitar body such that upon securing the brackets together the neck is secured to and fixed in proper alignment with the guitar body. The brackets each define a pair of rows of interlocking undercut teeth with one of the rows of teeth on the second bracket being moveable in a transverse direction for selective engagement and disengagement with the mating teeth on the first bracket to allow the brackets to be moved out of engagement and the neck separated from the guitar body.
