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.

Great first tool!

By

Verified Buyer


I've been a guitar player for 40 years and have always done my own minor work on my guitars. But this year I decided to step it up and start watching guitar set up and repair videos on YouTube and buy professional tools needed for the jobs. That's where I came across Stew Mac. I thought their prices were awfully high until I read reviews on their high-quality tools and great support. I took their suggestion on what tool to buy first and bought their String Action Tool. This thing is high quality and well worth the $30 bucks. Don't waste your money on the cheap import tools you find on Amazon. I highly recommend this tool and the folks at StewMax. I can't wait to order my next tool and learn more from their videos.

This won't be my last Stew-Mac purchase.

I've been purchasing tools for years and I usually buy quality tools. They tend to last longer and do much better job. This String Action Gauge is the nicest I've used. It is quality x 10. It is a lot easier to use than a 6 in. ruler.

I just received the string action gauge from Stewmac. I used it to set the string height on my Gibson ES. It is an accurate, easy to use tool I should have purchased years ago. Buy one!

I guess I can make it work.

Seems well-machined, ...now, if I can find a way to lower the strings to improve the stiff action for my feeble hands, I'd be much happier. Bud

I started out thinking "heck, I can make one of these easily enough" . True, it only takes 45 minutes to lay it out, another hour to cut, grind, and scribe the marks, and another 30 minutes to black the marks so I can read them... what is that? 2 hours and 15 minutes? And, not as accurate?
Great tool, great price. I am glad I bought it.

I'm not a shop or repair person, I'm a collector of vintage guitars. I'm using the gauge to check and reset string action when I refresh the strings. It's great. Nick
