I recently ordered a new nut (part no 03295) for my 660/12 due to the nut slots in the original nut being far too far apart and not big enough for the D and A wound strings, which made the guitar impossible to play.
The original nut is really thick and comparing to two they are completely different in size, shape and slot spacing. I tried to replace it and as you can see due the the new nut being slimmer there is a gap between the nut and the neck which, when the strings are bought back to proper tension causes the nut to lean back away from the neck. How can I make sure the new nut stays flat against the neck and how do I fill the gap that the old nut has left?
I'm really at the end of my tether with the gutar to be honest, wish I'd never purchased it.
