The Digital Nut Slotting Gauge quickly and precisely measures the heights of the strings over the first fret so you can file nut slot depths more accurately than ever before. That means easier, more consistent playability that you can custom-tailor to individual instruments and playing styles. No more guesswork or "eyeballing" the string heights, and no more searching for elusive combinations of feeler gauge.

Display measurements in inches or mm with an accuracy of 0.0005” (0.01 mm). Requires one 1.5V alkaline button cell battery (not included).
