Thanks for the feedback, dozy and Simon! I'll email PitBull and see what they say.

I need to inspect the fretboard a bit more to see what the consequences would be of scraping the fretboard to level it, as in some places the height difference between the binding and the fretboard is up to a millimetre, so the frets at those places would sit a lot higher from the fingerboard if I level them to the binding.

Thanks again for the support and I'll keep you posted on how this progresses.
