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.

Precision Measuring Tool

By

Verified Buyer


This is another must-have tool enabling you to properly setup a guitar's action. It measures string heights in thousandths and has SAE measurements in 32nds and 64ths for string height, bridge saddle height, saddle slot depth, fret slot depth, nut height, pickup polepiece height, etc. The front side of the tool has scale markings on three of the four edges allowing for different approaches to making the measurement. The back side of the tool has a handy conversion chart from 1/64th of an inch up to 1 inch in 1/64th of an inch increments. The table converts to decimal inches (to four places) and decimal millimeters (to two places). This is one fine precision measuring tool!

Easy to Use Gauge

Much easier to read than my steel ruler and I don't have to convert everything to 64ths. Should have bought this ages ago.

Even if you only work on your own guitars, getting the setup right after restringing, fret work, nut or bridge work, it is essential to get the string heights right for action comfort and intonation. This String Action gauge is a precision tool that eliminates the guess work. So accurate it make quick work of setup times...a must have for any string instrument work.
