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.

Handy piece of kit

One very handy little tool

Like many folks, I suspect, I made do with a pocket rule or sometimes even strings of differing gauges when doing setup work. I finally broke down and treated myself. It really does work better, has lots of different scales with which to measure and works great. Wish I'd just gotten it years ago.

This gauge means that you can check your string action height with a quick glance. Brilliant.

Awesome Gauge

Spent months to look for a stainless steel ruler but can't find anything work. This solved the problem and it works as it should and nice and handy. Might get extra sets to put it in my other guitar cases.

String Action Gauge 0670

I normally use dial calipers and a little metal scale, but those are kind of clumsy. The string action gauge is, in my opinion, much easier to use because it is specifically designed for the task. This definitely gets a thumbs up from me.

Excellent and Indispensable Tool

I've been trying for years to use a small ruler to measure string height and it was an impossible job until I discovered the String Action Gauge. What a difference in ease of use and accuracy. Every guitarist and techie should have one!
