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.

An Excellent Tool

By
(Customer's Reviews)


This tool assists you in measuring string action height, but it doesn't just stop there you can use it for accurately setting routers or any plunger cutter, it also serves as a miniature ruler, a measurement converter and has numerous uses. It saves you valuable time and it is one of these tools that once you start using it you don't know how you managed without it, a must have tool and very good value for money.

Make it easy on yourself

By
(Customer's Reviews)


You can cetainly get by with a precision ruler, Starrett caliper, feeler gauges, etc., but if you're doing more than one setup make it easier on yourself and get this measuring tool. I gently used 3M 401Q 1200 grit wetordry paper to relieve the sharp edges, and to make a very minor correction on one side of a scale.

Super Useful Tool!

By

This guage is great! I use it on EVERY setup, new nut install, etc. I've got 2 of them. One is worn out a little (hard to see the numbers on it due to LOTS of use). If your doing setups, you GOTTA have atleast one!

Not as good as I'd hoped...

By
(Customer's Reviews)


For the money I think it is not of great quality. Also measuring in 10ths is not as accurate as 64ths. It's only kind of useful. I should have looked more carefully before I bought it.

I have a lot of archtop guitars. This tool allows me to adjust the action very quickly and the slope of the bridge.

Action Gauge

By
(Customer's Reviews)


Bought the imperial version a good while back. Use it all the time for string action measurements, so for that it's 5-stars. Ideally, I'd keep the string action side the same (inch fractions, like how we measure strings) and have a metric ruler on the opposite face.
