A tuning device includes a tuner housing extending from a string instrument, such as a guitar, with an integral orthogonal threaded mounting portion mounted in a peg head aperture. A tuner rod extends concentrically through the tuner housing and has a distal end with a transverse interior passageway extending at the end of the housing. A loose clamping pin or screw extends concentrically in the tuning rod to the transverse passageway. After a string end is pushed through the passageway and drawn taut a lock knob or the hex-headed screw at the tuner rod opposite end is threaded into the tuner rod forcing a separate or integral clamping pin against the taut end of the string and to clamp the string in the transverse passageway. An internally threaded tuning knob adjacent to lock knob or hex-headed screw is rotatable on outer threads of the tuner rod at its proximal end to move the tuner rod longitudinally inward in the tuner housing pulling with it the clamped string. This action tensions the string to the proper desired pitch. Flattened portions on the tuning rod and tuner housing permits non-rotative longitudinally movement of the tuner rod. A guide disc on the tuner device adjacent the passageway guides the string into the passageway initially during the tuning. Spacers are provided under a flange on the mounting portion to assure that the strings exit at a proper angle to the guitar finger board. |
