Dan025 said:but it may have warped after the parts left the plant. as far as how you describe the neck rising like a skijump or whatever that sounds odd. i don't know how you even do that to a finger board. i don't know what warmoths fret board fixtures look like but it would take a real screwup to mess up that badly and then for it to be fretted and the fret guy to not notice seems like gross incompetance and i'm not sure that much would get past QC and the techs who build it. it sounds almost like you have a rising tung. is there any visible line where the fretboard meets the neck?
Well as I said, I described it in a little exagerated way.
These things are differences of 10th or 100th of millimeters. You don't see it at first sight. You note when you try to get a good action and wonder why you never get there. Than you look at it in the luthiers way (all down the head along the frets) concentrate and realize what's wrong. These are slight alterations but they make all the difference. But with the fret job the luthier did, it turned out fine.
It is not that the fretboerd is coming off as you might think ("is there any visible line where the fretboard meets the neck"), it is simply a slight warping on the upper register.
On another neck (this was custom made, not from the showcase) only ONE fret was higher (I think it was the 16th or 17th fret).
So I had to file it down a little bit and recrown it. This I did myself, not the luthier. But it was hell, because these where stainless steel frets. Horrible to finish. The fret seemed to laugh at my file, it is a really difficult material to work with. So if Warmoth had check it before shipping it....
