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.

Not a technical guy w. this

I ordered this gauge to help w. string playability.
I'm not sure I'm positioning the gauge properly and reading it as well.
I suppose I should contact a tech guy so I can use it

Fast and easy (and the gauge was also) ;-)

I use to make gauges like this by scratching lines with an exacto knife on an old credit card but this gauge is more accurate and the different measurements on the other sides are so handy. I've set up three guitars with it and they are all so sweet now.

Needs to be bigger

By
(Customer's Reviews)


Bottom line is it works and seems to be accurate. But its hard to see some of the measurements.
It has been very helpful but i don't enjoy using it. if it were 50% bigger I would use it with no reservations.

Best tool for guitar setup

By

This made setting up my telecaster a breeze. Measurements are swift and simple as well as accurate. I don't think I've ever had my guitar playing as well as it is now. For what it's worth, this allowed me to easily measure out 3.5/64 for my string height!

Easy to read and use. Made set up much quicker. It is heavy duty metal and feels like it will last a long time. Recommended.
