Precision Luthier's Fret Rocker AND String Height Gauge in One Tool - Bright Anodized and Ultra-Flat for Deadly Accurate Results

Why pay for multiple tools? This one tool measures string height AND locates high frets Made of aircraft grade aluminum and hard anodized for a long life of service The four sides are used to measure between each group of 3 frets on a guitar. The long side is used on the low frets and as you move up the neck, the remaining 3 sides are used to bridge the groups of frets. If the tool "Rocks" on a set of 3 frets, you know the fret in the middle is high and it needs to be sanded or filed down. The only way to properly identify a high fret is to start with a tool that is deadly accurate. These tools are CNC milled then hand lapped on a machinist's surface plate to ensure the edges are FLAT, FLAT, FLAT Made for the musician who wants perfect setups every time without guesswork and without fret buzz
