Abstract: A single-tool step gauge provides for measuring or setting a preferred or desired height of a string above a surface of a stringed musical instrument, and includes a nut slot gauge, crown height gauge and string action gauge. The nut slot gauge includes a downwardly-extending tab, a first plurality of integrally-formed graduated length gauges that measure a nut slot height, and a first plurality of measurement indications corresponding to the first plurality of graduated length gauges. The crown height gauge includes a pair of feet, a second plurality of integrally-formed graduated length gauges that measure a fret crown height, and a second plurality of measurement indications corresponding to the second plurality of graduated length gauges. The string action gauge includes a base, a third plurality of graduated length gauges that measure a string action, and a third plurality of measurement indications corresponding to the third plurality of graduated length gauges.
