Totally professional in design and performance. Small, lightweight, this precision made machine fits guitar headpeices that will not take full size machines. The mini buttons provide more space for player’s fingers (even large fingers) to tune strings. Gear ratio is 14 to 1. Sealed in lubrication keeps the mini perfect for a lifetime! Includes 5/8” washers, bushings and wood screws.
Post hole size: 25/64" about 10mm
Note: Set screw holes may not line up on all models. New set screw holes may need to be drilled.
