Hi Gang,
I have a Fender P5 and am having tuning issues caused, I think, by friction on the string trees due to a steep break angle of the nut. Any ideas?
Lubrication.
Get a tube of graphite powder from the key making section of a hardware store. Squirt it into the nut slots and on top of the strings where they touch the trees.
That'll get things moving more freely. Reapply as needed.
