Grover Rotomatic 103C guitar tuning machine heads are a marvel of engineering and design. Rotomatics have a gear ratio of 14:1, and a housing that provides optimal bearing for worm, gear and string post. Precision-cut worm and gear serve up perfect meshing, eliminating backlash and slippage. A countersunk tension screw lets you customize tension to your personal preference. The Rotomatic's gear box is permanently lubricated, giving you a lifetime of trouble-free operation. Washers, bushings and wood screws are included with this set of six Grover Rotomatic 103C vintage-styled guitar tuning machine heads.

Grover has been keeping the world's finest stringed instruments in tune for over a century. Grover started out in the late 1800's producing banjo and guitar tuning machine heads. Eventually the company expanded into making tuners for mandolin, dulcimer, ukulele, violin, pedal steel, and bass guitar. Inventor of the enclosed, permanently lubricated machine head, Grover tuners are original equipment on many of the world's finest string instruments. Grover employs only the finest materials and manufacturing methods, and stands behind their products with their lifetime warranty
