Abstract: Methods and apparatus for providing a high performance stringed instrument. In one embodiment, the stringed instrument comprises an electric guitar constructed entirely of sheet metal, with the body and neck permanently joined together to produce a one piece (unitary) style guitar construction. This method of construction results in improved overall consistency of the product. In particular, the construction utilizes a substantially homogenous material throughout the guitar and further includes a stronger, stiffer and straighter neck that allows for a more consistent sound than is possible using traditional manufacturing materials such as wood. Such a construction also offers improved sustain of string vibration, an attribute that is highly desirable to guitar players. The incorporation of a unique supporting structure into the headstock contributes to a unique warm timbre when played that has heretofore been unachievable in combination with improved sustain characteristics.
