String Action Gauge

This business card-sized measuring tool is very useful, includes a different measuring rule on each edge. 

With easy-to-read string height measurements along the bottom edge, a 75mm traditional ruler on the opposite edge, and for really tight spaces, each of the smaller edges shows tiny rulers.

Our luthiers use this tool for a variety of jobs, from its main purpose, string height to measuring nut height and even setting up the router table.

  • Extremely precise, all in one measuring tool for achieving the perfect string action 
  • Stainless steel makes it lightweight and highly durable
  • Metric option has full conversion from Metric/Decimal/Fraction on the back and the imperial option shows Fraction/Decimal/Metric


  • 89mmx51mm
