HOW TO DEAL WITH GUITAR BUZZING ?

Solution: Some neck panels can return to their original shape by themselves according to climate changes, but most of them need to be repaired by physical humidification. If the deformation is too serious, they can only be returned to the factory for repair. If the neck is raised, straighten the neck with a hex wrench. If the overall panel is low, you can raise the lower nut or replace the lower nut to re-adjust the feel.

2) The height of the frets will vary due to weather or human factors, and the raised frets can easily collide with the strings, resulting in scratches.
Solution: use sandstone to grind, or use a small file to cut off the protruding part, but both methods are easy to damage the flatness of the frets. If the economy allows, it is best to find a professional master to replace the frets .
