One fret rocker tool for finding uneven frets. Hold one side of the tool across several frets, perpendicular to the fretwire. Start with the longest side, and progress to shorter sides to narrow down and identify uneven frets. Made of solid 0.1 inch thick steel with precision edges and wrapped in a non-slip finish. Each side measures approximately as follows:
3.9 in. / 99 mm.
3 / 75
2 / 50
1.3 / 33
.8 / 20
NOTE: Do not "rock" the tool forward and backward - its sharp edges will gouge the fretboard.(H)
