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.

Want to make sure your string height is spot on? Get this high quality string gauge and you won't have to guess what you're doing. Adjust the string action and check the relief of the neck. This will do both. You cannot do a decent setup without this. It makes a 6 inch metal ruler obsolete. Do it right! Get this string gauge.

Perfect Gauge!

This IS the one to get! There are others available at much cheaper prices, but the quality is not the same at all. The metal is thick and has some nice weight to it. The markings are very precise.

Plenty has already been said in these reviews about the String Action Gauge. All I can add is, I shopped around to find an off-shore version for a little less dough, and they're all cheap knock-offs (go figure). Finally, I sprung for this one, and I'm glad I did. This is a sturdy, heavy, quality tool that will easily last a lifetime. The markings are FINE, crisp, and easy to read. Very happy to add this to my bass setup tool box.

Had a cracked trussrod nut on my LP. Upon closer Inspection the threads on the trussrod were iffy. I ordered the 10-32 Die, trussrod nuts, and the string action gauge. Should have figured this out 10 years ago. Thanx, she plays real sweet now!
