A device for use in tuning a string of a musical instrument includes a pinion gear which is connected with a rotatable shaft. A worm gear is rotated to effect rotation of the pinion gear and shaft about a central axis of the shaft. A sleeve encloses a portion of the shaft and is rotatable relative to the shaft. The sleeve includes string holes which are alignable with string holes in the shaft. The shaft has recesses formed at end portions of the string holes in the shaft. The sleeve extends across and encloses the recesses formed in the shaft. The sleeve and shaft are relatively rotatable from a first spatial relationship in which the string holes in the sleeve are aligned with the string hole in the shaft and a second spatial relationship in which the string holes in the sleeve are offset from the string hole in the shaft. Knurling is provided on the outside of the sleeve. |
