US Patent 8927836 Adjustable and removable string instrument neck

This system provides an acoustic string instrument that allows a musician to carefully adjust the height of the fingerboard relative to the body of the instrument by means of two slidable machined inserts that are inserted into the neck and body of the instrument. The inserts are adjusted by a hex wrench inserted into the back of the body of the instruments. The neck can also be completely removed by disengaging the inserts for transport.
