The neck seems to be set well. The guitar plays and intonates well.
The other side of the neck isn't so bad. It looks as if there may have been a problem taking the neck out at one stage and the side was damaged. The binding on top has a slight nick in it too.
I'm planning to keep it as a natural finish as i like the contrast between the flame top and the darker sides. Using a solid colour for the sides would be a way to hide the filler.
I'll consider my options. ;-) I might get used to it as it is! In the meantime I can work on refinishing the front and back.
