Bass Tuner Hole Options

Bass Neck Tuner Holes

Tuner bushings from different manufacturers are not always identical in size. If the tuner bushings you are using don't fit into the tuner routs fairly easily do not force them. It is necessary to open the hole up slightly. Headstocks broken as a result of forcing bushings into them are not covered under warranty.
