I have a 37' Kay and have had the fingerboard reworked and it came back from the luthier pretty much "flat". It notes out fine with some slight "buzz" along the strings in all the mid positions. He also repainted the fingerboard since it had practically no finish on it from years of wear. I know that the best thing to do is to take it back to another luthier which I plan to do. In the mean time... Is it possible to work out some of the slight buzz with some extra fine sandpaper? Could the new paint / finish be causing it? Could I just lightly sand the neck even with steel wool to see if it helps? Any suggestions are appreciated.
