ABSTRACT:
A gearless tuner for a stringed musical instrument comprises a generally cylindrical housing for mounting on the instrument including an axial opening extending therethrough; a knob core sized for insertion into the axial opening in the housing including a threaded aperture extending axially therethrough and an annular ring for interacting with the housing to maintain the knob core in the housing; and an elongated slider extending into the axial opening of the housing and axially threaded into the aperture for securing one end of a string of the instrument and drawing the string into the housing when the knob core is rotated with respect to the housing to tension the string, including a string opening through the slider substantially parallel to the direction of the string on the instrument for receiving the string, and locking means both for allowing the slider to move axially with respect to the housing and preventing the slider from rotating with respect to the housing.
