To pinpoint those pesky high frets, and check the final height after you've redressed or replaced them, reach for the Fret Rocker! Our 4-in-1 mini straightedge spans three frets and "rocks" to indicate uneven fret heights. Precision-machined for accuracy to .0015" per foot, the 4", 3", 2" and 1-5/16" edges make it versatile for any fretted instrument, from basses to guitars to mandolins.
