A folding stringed instrument (1) has a narrow body (2), a neck (3) with a fret board (4) and strings (5). Tuning pegs (6) and a bridge (7) are provided on a front face (8) of the body, together with an optional microphone pick-up (99 and a stand (10) at the end of the body. The neck and the body are pivotally connected about a pivot (11) set back from the face, whereby the neck can swing under the body. Centrally this is of wood board (12) with a deeper aluminium edging flange (13) for stiffness, enabling the neck to be swung against the board between opposite sides of the flange. The pivot (11) comprises a pin (14) between the opposite sides of the flange and a secondary roller (15). The neck is formed of a shallow aluminium channel (16), with the fret board secured to one side and a closure plate (17) closing the channel. Trunnions (18) extend from the channel at the body end of the neck for pivotal connection to the pin (14). At the head end, the web of the channel is cut away and the flanges (19) bent inwards in a lazy Z manner to support a further pivot pin (20) for a primary roller (21) around which the strings pass. A non-shown bearing is provided for the roller (21) on the pin (20). |
