Electric and acoustic guitars that have (3) tuners per side headstocks will typically experience tuning problems associated with the “D” and “G” strings hanging up and binding at the nut due to their extreme string path angles.

The Guitar NutBuster® re-aligns and straightens the string paths as they exit the nut while simultaneously locking all (6) string tensions together, preventing string/nut hang-ups or bindings from occurring and keeping the guitar in tune!
