Eliminate String Buzz One Fret at a Time Need to plane down a high fret or two? Don’t break out the leveling beam just yet — MusicNomad’s Fret Leveler Diamond U-File hones in on your problem frets, negating the need for a full fretboard level. The files in this set function just like a fret rocker, with three differently sized files included to span across any three frets on your instrument’s fingerboard. However, unlike a rocker, the center portion of the design features a diamond abrasive that’s perfectly level with the two smooth outer edges. This allows you to cut only the high fret and bring it back into line with the rest of the fretboard.
