(There may be a thread on this already, if so, please paste it here as I could not find it.) I just had adjusters installed on my bridge with a FC by a professional luthier. The work is flawless (thanks Upton). However, I noticed that after tuning to pitch, there is a very slight angle towards the scroll in the gap between the adjuster and the wood on the E side. I have lots of graphite in the grooves and the grooves are nice and smooth and the feet are where they are supposed to be, but I can't seem to get the gap 100% parallel. The angle is very slight, in fact, unless you get right down there and with very good light, you can't see it. Is this a problem? Should the gap between the adjuster and the wood be exactly parallel?
