Nut lubrication

Applying a dry lubricant, such as graphite or a proprietary product, to the slots in the nut so the strings can slide freely.

Tuning problems that appear only after bends or tremolo use are usually the string binding in its nut slot rather than a fault with the tuners. Lubricating the slot lets the string return to its correct tension on both sides of the nut, which fixes the classic symptom of a guitar going sharp on the wound strings after heavy playing. Graphite from a pencil is the traditional solution, and purpose-made products last longer by leaving a dry film rather than an oily residue that collects dirt.

Example: A guitar that goes sharp after tremolo use until the string is bent, cured by rubbing graphite into the nut slots, needed nut lubrication.
