Abstract: A guitar having a body, a headstock, a neck, a plurality of strings, and a tremolo device including at least two bevelled-slotted pivot points. The bevelled-slotted pivot points have a top and bottom bevel which lowers the friction of the bevelled-slotted pivot points against the v-shaped grooves of the studs. The tremolo includes spring claw fasteners that support the tremolo system and allow the tremolo height or position to be adjusted without affecting the structural integrity of the tremolo. A tremolo arm assembly is provided which allows the tremolo arm to remain in a fixed position to prevent interruption of play.

Abstract: A guitar includes a tremolo device disposed on its body. The tremolo device engages and varies the tension of one or more guitar strings. There is a tremolo arm which is precisely attached to the tremolo device for movement thereof without unwanted play. In a preferred embodiment of the invention the rotation resistance (i.e., pre-load) between the tremolo arm and the base plate is variable and can be set and maintained even under severe use conditions.

Abstract: A guitar includes a body, a headstock, and a neck disposed between the body and headstock. There is a tremolo on the body and a tremolo anchoring system attached to the body. A spring is operatively associated with the tremolo and with the tremolo anchoring system for biasing the tremolo for tensioning a string extending between the tremolo and the headstock. A tremolo-level-adjustment member operatively associated with the spring variably fixedly tensions the spring for variably biasing the tremolo for variably tensioning a string extending between the tremolo and the headstock. The tremolo-level-adjustment member includes a pair of nuts, which nuts are spaced apart from each other, and each of which nut is movable relative to the body for variably fixedly tensioning the spring. There is likewise a fastener for use with the present guitar and with existing guitars.
