Independent shopping perspective
Grover’s gold Locking Rotomatics 106 Series combines an 18:1 ratio with a cam that locks internally during tuning. After you feed the string through and pull it to tension by hand, turning the peg activates the locking action. The workflow keeps attention on setting pitch by ear. Grover describes these machine heads as retaining tune under heavy playing conditions and positions them for guitars with existing peghead holes.
