Fret Slot Depth Gauge

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. 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.

String Action Gauge

Usually I set up my guitars basically by trial and error and bits of paper with pencil marks on them for string height etc. However I recently purchased the String Action Gauge and it makes things very much simpler and much more consistent. As a result I have reset up 4 guitars since getting it and eventually I'll work my way through the rest.

Gotta have a dozen!

Why? So I'll have one for the rest of my life if they quit making them - that's why! One would easily last a lifetime on the shop table, but I want to carry one in my billfold like a credit card and I'm afraid the ink and markings will wear off (probably won't though). This is the single most all-round valuable tool on this website. I promise!

Handy Little Tool

I was having some tone issues after changing the strings and adjusting the action on my Godin 5th Avenue. I tried to adjust every string just above buzz, but it just wasn't quite right. With this little tool, I had everything right within 2 minutes. The price is way less than I would have paid for set-up. Be sure to watch the instructional video. That was helpful as well.

String action gauge

Only a very simple product, but a very necessary one if you want to get into setting your guitar up properly. The quality of the product is excellent with all the markings clear and accurate. The rudimentary instructions and benchmark values are also very helpful. The purchase interface (the website), considering I am buying everything from "overseas", is second to none. I have bought before from firms in the USA and have had endless problems. This firm has got it right. Thanks for the service you offer.

good but not great

i would rather have the gauge mirrored on the backside than have a fractional to decimal conversion table. This would allow you to flip the gauge when working on the high E side and have the gauge near the string and your eye. instead of having to look down over 5 other strings and try and judge the height accurately. if you try and do this with the gauge as it stands you will not be able to use the string height markings near the nut.

Super Setup Tool

This gauge has been incredibly useful! It's the easiest way to measure string height at any given fret. I got the metric version, and I use a table to convert to inches. Highly recommended!

Great for setups

Great tool for quickly measuring string height after making saddle or truss rod adjustments. It not as active as a file or saw but it's extremely handy to have available. The conversion chart on the back was a nice use of space as well.
