ABSTRACT:
A device for clamping and tuning strings which extend longitudinally between and past the nut and bridge of a musical instrument includes a base. The base includes a plurality of threaded shank elements. A plurality of threaded nuts are each threaded on a respective shank element. A plurality of actuators are each threaded on a respective threaded shank proximate to a respective threaded nut for selectively applying clamping pressure to a string position between a respective actuation means and threaded nut by rotating relative to a respective threaded nut and shank element. A plurality of cams are provided, each rotatably mounted on the base proximate to one of the strings at a position past the portion of the string between the nut and bridge for moving longitudinally relative to the extent of the string while displacing the string in a direction generally lateral to the longitudinal extent of the string when the cam is rotated for adjusting the pitch of the string by adjusting the tension of the string.
