Some questions:
Question 1:
The nut came off in transportation I guess.
This is a photo of the but just resting there:
and these two are photos of the nut, notice the slot where the nut is supposed to rest
.
Notice also that some of the timber came off where the nut is supposed to rest.
I think I can just fill that with some timber filler to patch it up?
I'd imagine that a drop of super glue will hold the nut in place, however I was thinking if perhaps I should make a little reinforcement just behind the nut, towards the tuners, to create a slot for the nut to rest? (think of a classic fender precision bass nut, for example, it sits in a slot).
I have drawn an orange rectangle on this photo to show where I am considering adding the timber to create a slot.
I guess if I go ahead with this, the piece of timber that I am adding will need to have a little round cut so that I can still reach the truss rod with an allen key...
Or a bit or glue would be enough, between glue and string tension pushing downwards? (It was just glued in the factory after all)
