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.

String Action Guage

Amazed how handy this gauge is to have around. Already used it on my guitars, mandolin, ukuleles, violin, mountain dulcimer, and just today on a psaltery that I am refurbishing. So much easier to use and read than a conventional ruler. If I ever lose this one, I would have to buy another.

This is the best measuring tool for setting your string action. Sits across a few frets to avoid rocking. A must have tool.

Like me... you might have thought your ruler is good enough...

One day I took the time to measure my ruler with a verneer caliper and discovered that it was extremely inaccurate for measuring string height. So I finally splurged and bought this tool. IT'S AMAZING! I DON'T KNOW HOW I LIVED WITHOUT IT. Not only is it accurate, it's soooooo thoughtfully designed, and user friendly that it improves my productivity noticeably! This tool paid for itself many times over the first time I used it!

String Action Gauge...

This is a very useful tool to use, prior to setting the under-string radius at the bridge. I use this as a starting point when setting up the height of both E strings, then use the string gauge radius tool to adjust the A,D,G,B strings accordingly... I always fine tune after the height and radius have been set... I would highly recommend this tool, especially if you are doing a lot of set ups...
