Tuner Hole Options

Guitar Neck Tuner Holes

Our standard tuner holes are an 11/32" straight bore. This matches up to the push-in grommets of the standard Vintage Style tuners (some copies may be different). When you purchase a new Warmoth gutiar neck, we can ream our counter-bore the tuner holes to any of the sizes listed below, at no additional charge.

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.
