String Action Gauge

About This Item

Fast, accurate measurements for setups.
Our String Action Gauge is a "Swiss Army Ruler" for setup adjustments on any stringed instrument.

This pocket-size stainless steel rule has become a luthier's favorite in busy shops. It's the best way yet to get vital measurements on acoustic and electric instruments.
• String height
• Bridge saddle height
• Saddle slot depth
• Fret slot depth (unbound fingerboards)
• Nut height
• Pickup polepiece height


No more "three-and-a-half-64ths or 3/32" plus one of those little lines." This gauge measures in ways that regular rulers can't.
—Dan Erlewine

Developed here at Stewart-MacDonald by Dan Erlewine and Don MacRostie, the gauge features a progressive string height scale: simply slide it across the frets and read the measurement under the string. It's faster to use than any ruler, and stays parallel to the fingerboard—much easier than trying to hold a ruler perpendicular to a rounded fret.

StewMac's String Action Gauge has two models (sold separately) for measuring in inches or millimeters. The string height markers are graduated from .010" to .140" on the inch model, and from 0.25mm to 3.50mm on the metric version.

The back of the gauge has a time-saving fractional/decimal/metric conversion chart.

The String Action Gauge is made of durable stainless steel with precision-etched markings, and fits right in your pocket.

Tip: You can use the gauge to set router depth, instead of a shop ruler. It sits solidly on your router base, with the scale right where you need it.

Metric Version

By

Verified Buyer


The metric version is silly! The metric rule scale is strangely divided into 25mm increments and the string height scale is incremented by 0.25mm. Really, fractional metric, wouldn't 0.2mm make a lot more sense? It is a base 10 system used by all the world bar one country. Beware of US Metric.
I've owned this for 3+ years and used it as a small straight edge and square only. And it rusted.

Essential setup tool!

By

Verified Buyer


This is the most useful tool I've ever bought! String action, pickup height and other measurements are easy to task. Lines are easy to see, a mile better than "alternatives" offered around. Mine is metric. You can carry it anywhere, even in your wallet. Six years since I bought it and it's still perfect. Thanks!

A must have.

Up to this point, I have always used a 6in scale to measure string height. With age creeping in on me my eyesight is not the best. This gauge is easy to use. This is a must-have item for anyone doing guitar repairs and setups. Thanks Stew Mac!

A much needed tool for any luthier. Far too expensive though.

String action gauge

These little gauges are very finely manufactured and very precise. The markings are excellent and easily visible to gauge string height above the fretboard. I bought the gauge in inches and the metric gauge. The steel is thin but strong and very precisely finished. They do the job very well.
