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.

elegant and essential

To use this tool an Optivisor or equivalent magnifier is essential, but that's my vision issue, not a flaw in the tool it's self.
The action gauge is very well made and perfectly sized for it's function.
It's an elegant little thing, one of those rare tools with a set of uses well beyond it's intended role:
I've used it as a fret rocker and as a drafting tool and for tool set-up ...
In my shop it will probably never see the inside of a drawer.

This is a very high quality measuring device. Thick steel with easy to read markings. The fractional to decimal conversion chart on the back is handy as are the left/right 1/64 markings for things like pickup height adjustment.

String Action Gauge

As an aged "on and off again" band musician, I have never worked on my own instruments. I decided to learn how to set up my own guitars and banjos instead of paying someone else to make the adjustments. With so many tutorials on the internet, and tool availability, i have been successful and the "string action gauge" has been a great measurement tool to have on my bench.

Extremely handy and accurate gauge

By

Verified Buyer


I have quite a few guitars and I'm pretty set in my action height preferences. Very often, when I look up the recommended string height for one of my guitars, the measurements are metric (which I prefer). This gauge lets me check and adjust using those metric results. It's so much easier to adjust by millimeter than it is by 64th's! This item is made from a heavy gauge metal and is perfectly flat and true in every way. This is easily the best gauge of it's kind you're ever likely to find. If you need it, buy it. You won't be disappointed.

Excellent setup tool

After using a 6 inch steel ruler for years, I tried some of the generic, cheaper action gauges on the market. Basically flimsy and hard to read. I finally bit the bullet and bought one of Stewmac's offerings. The difference is like chalk and cheese. An excellent tool for the job.

This has so many uses, it was well worth the money. I am a fashion designer, I don't know how I would have been able to make the 6 guitars I have made this year without the excellent tools from StewMac.

A Handy Tool

This string action gauge is the best tool I've used on my electric bass for measuring first fret action, neck relief, and string action at the 17th fret. It's even handy for measuring pickup height. I'm glad I ordered one.

I purchased this for home use and have been wildly impressed for its accuracy . The money spent on this is well beyond the frustration of any other attempt at home measurement. Solid purchase
