Finished the copper shielding today and attached the fretboard while I wait for some black pickup covers.
When I was oiling the fretboard I noticed a fine crack in one fret as per the photo.

I would appreciate some advice how to fill the crack. I was considering just dropping in some super glue.

I don't think the fretboard is rosewood. I seems a bit darker and softer than rosewood. The original advertisement for this SR1-Ash body read as follows:
- Maple neck ("C" Profile) and Rosewood Fretboard
- *Blackwood (Engineered Rosewood) Fretboard for international orders.

I think maybe I have scored the engineered stuff from Adam in error. I am aware of the international rosewood issues.
