This innovative tool reproduces the fretboard relief for instant localized fret leveling with the strings on™. No need to straighten the neck or remove the strings for leveling, unless you still want to level the frets the old way or/and with the neck set straight. With Buzz Killer single fret and spot leveler you can fix buzz very quickly. You won't need to stop playing! You can refinish the frets later, if not strictly necessary like on an average shop-repair. Its base features a sequence of abrasive and protective zones that will file down only the higher fret(s). You can simply place the base of the tool on an good working area adjacent to the buzz and adjust the tool so that the surface of the base comes in contact with all of the frets below. Then, place the tool in the buzzing area and level it. If the area is straight, the BUZZ Killer can be used straight as well. It can work also like a "copy and paste" tool that replaces the bad working shape of a fretboard area with a nearby good one. It comes preloaded with #320 grit abrasive plus a refill roll.
