These guitar machines are a triumph in engineering and style. The housing provides a maximum bearing for worm gear and string post. Gear Ratio is 12:1. Worm and gear are precision-cut for perfect meshing. This eliminates backlash and slippage. Countersunk tension tension screw permits players to regulate turning tension to any degree. Gear box has a special lubricant for lifetime, trouble-free service. Includes 5/8’’ washers, bushings and wood screws.
The Grover 102 Guitar Tuning Keys are the finest machines available and are used by many leading manufacturers. Remarkably smooth mechanism, completely enclosed and self-lubricating with a 12-to-1 gear ratio. Nickel finish.
