Claim Text:
1. A hemispherical pull tuning device for tuning a stringed instrument comprising; an instrument attached receiving component with one or more boreholes that are internally threaded on one end and horn shaped on the other end; a rotating component with external threads on one end for engaging an internally threaded receiving component borehole, and having a knob on the other end for user activated rotation; where the rotating component consists of a small diameter through borehole, and a larger diameter shallow borehole on the knob end; a low friction component that permanently resides in the shallow borehole in the knob end of the rotating component, that supports one end of an instrument string and allows the rotating component to turn while the supported string incurs minimal rotation; and an auxiliary non-ball end string terminator component which provides for string attachment to the tuner when non-ball end strings are used.
