The Buzz-Off Fret Leveling Kit® from J.S. Bogdanovich Guitars is used to find and level high frets in order to eliminate fret buzz. The kit is composed of a hardwood sanding block shaped to fit frets, a 3”, and a 2” straight solid steel pin for flattening, a piece of 220 and 400 grit sandpaper, and a small piece of steel wool. The pins are used to check flatness of the frets relative to each other. The 2” pin is for the upper frets where they are closer together. Place the pin across three frets and try to rock it back and forth. A clicking sound will reveal a high fret. Mask off the fingerboard with tape and lightly sand down the fret using the hardwood sanding block starting with 220 and progress to 400 grit sandpaper. Check for flatness with the pin again. When flat, polish with #0000 steel wool. Kit is not used for neck flattening.
