ABSTRACT:
The clamping apparatus includes a row of clamping elements, each two adjacent elements having one of the guitar strings disposed therebetween. An adjustable-length bolt extends through the clamping elements to create string-clamping pressure determined both by the rotated position of a bolt head and the position of a cam, the latter being mounted at the end of the adjustable-length bolt remote from the head. In accordance with the method, the head is hand-turned to cause seating of the clamping elements on the strings, this being while the cam is in a predetermined position. Subsequently, the cam element is shifted to another predetermined position that generates a large clamping pressure on the elements to clamp the guitar strings against longitudinal shifting despite the presence of large forces such as are created by tremolo action and by bending of the strings. An adjustable-height zero-fret element is provided adjacent the clamping elements to determine string height.
