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.

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!

This is a great piece of equipment...very strong and easy to read and to use...I was having a difficult time finding someone local to adjust the action on my ukulele...I did research watched some tutorials...bought this and some nut files...with a little patience...in about 15 minutes I was able to make my uke so easy to play...and no fret buzz

Best string gauge on the market

This is so much better than those cheep China ones. It's thicker and the etching is much more accurate. Spend a couple dollars more and get this one. You won't be sorry. Shipping was fast and the packaging was good. I would recommend this to a friend.

I bought this tool to help set up a used guitar that needed a lot of work. The String Action Gauge help speed up checking and making adjustments. I use to use a six inch scale but the marks were hard to see especially on the middle four strings. Love this tool wish I had bought it five years ago.

I purchased the string action gauge recently and found it to be solidly built and really easy to read. I also purchased the tech wrench set and the multi spanner which worked perfectly and had an excellent finish. These tools are built by guys with a lifetime of experience as luthiers and should be in every guitar players tool set to keep their guitars in perfect setup.
