Well, I decided to try leveling the frets on my P-Bass clone yesterday. I have it set up with very low action and I was getting some fret buzz; I had 3 high frets. I bought a set of X-acto files, very fine...for jewelry work. I went up the neck with a straightedge and located the high frets (the straightedge will use the high fret as a fulcrum and "see-saw" when a high fret is between 2 frets of the correct height). I also deburred the fret ends. I removed the neck and masked it to avoid scratching the finish. I was surprised at how easy it was to do this; I have never done any fretwork before and was kind of intimidated by it. Anyway, the whole operation took about an hour and the results are immediately evident. There are no more buzzes and there are no burrs on the ends of the frets. The bass plays like a dream. I have done my own truss rod adjustments and bridge adjustments for years, but I had never tried any fretwork before. If it wasn't for the information I received on this forum, I would never have had the confidence to try this. Thanks, everybody.
