Fender 992006000
Deluxe Fluted-Shaft Bass Tuning Machines

Set of four polished chrome tuning machines for use on most modern Precision Bass® and Jazz Bass® guitars. Wider at the top than the bottom, the fluted shafts force the string windings downward and keep them tight, resulting in a sharper and consistent break angle over the nut, creating increased sustain and better tuning stability.
