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.

Should be a useful tool. I tried it on my Martin HD-35 and found the truss rod too tight and made adjustments. I see many uses for this tool on my 7 other guitars as well as those of my grandson.

A great simple tool!

Not only is this a very simple and accurate way to measure your action, but the instruction sheet has just about all of the information you need to get a good setup. If you are new to guitar setup you should get one - you should probably get one even if you aren't new to it.

Also, great service and super fast shipping as usual from StewMac.

Exactly what I wanted, and was looking for. I set my strings to a proper height, and playing is so much better now. Very satisfied.

Best in the industry

This little card is the best in the industry. I'm on my third one in five years, as they seem to walk off stage or I loose, don't know. This time I'm buying some stewmac magnets and screwing them in my work box so it always has a solid home! I use it almost everyday on tour.

At some level it's just a ruler, but one that has been specifically designed for the unique issues around setting string height. Nothing fancy, but very well designed and fits the "right tool for the job" description. Big fan!
