Unlucky indeed, Andyxlh! Let's see what PBG says - asked them for third replacement or a refund. As a first build, I was expecting to have to do a lot of work and make mistakes, but what is going on in the fretboard seems like it either can't be totally fixed, or that the work involved in doing it is way beyond what PBG says I should expect from the kit.

Simon, I measured both bindings on the top and bottom and they are both 5mm. It looks like the fretboard is the issue there. Some frets are raised from the fretboard at the binding, some aren't. From what I can see, it looks like it's the fretboard that for some reason is set higher than what it should, and they tried to "fix" the issue by carving the end, with the results you can see above.

I've taken another shot to try to show the fret ends - you can see a couple of them lifted from the binding, I hope it helps:



(apologies about the angle and the lack of precision with the ruler, I was holding everything with one hand and the phone with the other!)

Cheers!
