Abstract: A folding stringed instrument has a narrow body, a neck with a fret board and strings. Tuning pegs and a bridge are on a front face of the body, with an optional microphone pick-up and a stand at the end of the body. The neck and body are connected about a pivot set back from the face. The pivot comprises a pin between the opposite sides of the flange and a secondary roller. The neck is formed of an aluminum channel, with the fret board secured to one side and a closure plate closing the channel. Trunnions extend from the channel at the body end of the neck for connection to the pin. At the head end, the web of the channel is cut away and the flanges bent inwards in a lazy Z manner to support a further pivot pin for a primary roller around which the strings pass.
