A guitar has a separate body and neck each made of a metallic frame combined with a mass of structural foamed plastic. A solid joint, involving metal to metal contact of the two frames, is provided between the body and the neck and is readily unmade to allow disassembly of the neck from the body for repair or replacement of either the body or the neck. The two frames provide a continuous metallic span from the nut to the bridge to inhibit bending under string tension and also to enhance sustain by reducing damping. The external surface of the neck and body plastic masses may be given a grain effect, color and finish causing such masses to closely simulate wood, yet the use of wood is entirely avoided to avoid its disadvantages such as its tendency to warp, crack or otherwise deteriorate with age and changes in temperature and humidity.
