Instructions for using the Sperzel Drill Guide
- Place drill fixture in hole of headstock for tuning machine.
- Line up the straight edge of the fixture to be straight with the edge of the headstock, or in line with each other.
- Using a threaded bushing, screw this onto drill fixture to hold it in place while drilling pin hole.
- Remove and repeat for each tuner.
Sperzel® locking tuners stay in tune while eliminating the hassles of restringing. The string locks in place, thus eliminating redundant winding. Sperzels are the first significant advance in guitar tuning capabilities. Another beautiful thing about the Sperzel Tuner is the ability to reverse peg head directions, making it a near universal fit tuner, with just a flathead screwdriver.
