Q: My guitar is buzzing, but only on the open strings. How can I fix this?
A: Open strings buzz because the nut slots are cut too deep. There are two solutions, both of which are best handled by a qualified technician:
- Replace the nut with a new one that has its slots cut to the appropriate depth.
- Shim the existing nut to raise it, and the string height, up very slightly.
In either case, the guitar should then have a complete setup to ensure that it is playing as well as possible and that the action, intonation, etc., is optimized for your playing style.
