Details

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. 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.

Super Useful Tool!

This guage is great! I use it on EVERY setup, new nut install, etc. I've got 2 of them. One is worn out a little (hard to see the numbers on it due to LOTS of use). If your doing setups, you GOTTA have atleast one!

Good tool to have

Not as good as I'd hoped...

For the money I think it is not of great quality. Also measuring in 10ths is not as accurate as 64ths. It's only kind of useful. I should have looked more carefully before I bought it.

very usefull

I have a lot of archtop guitars. This tool allows me to adjust the action very quickly and the slope of the bridge.

Action Gauge

Bought the imperial version a good while back. Use it all the time for string action measurements, so for that it's 5-stars. Ideally, I'd keep the string action side the same (inch fractions, like how we measure strings) and have a metric ruler on the opposite face.

Essential

It makes the job of measuring the string height so much faster and clearer.

I have to agree with Martin Fuerstenau though, a version with metric and inches would be indispensable and would get a 10 star rating.

Not only do you save time in checking string height specs you can check a customers guitar instantly and get another repair out of it.

you NEED this, it's the one tool that I just cannot live without now.

Fantastic setup tool with a little drawback

By Martin Fuerstenau from Unterfoehring
(Customer's Reviews) Friday, January 06, 2012


I live in Germany. That means metric. I read a lot of guitar building books. That means metric and imperial. Therefore I ordered both - the metric one and the imperial one. Thats the drawback. I think it would be great to have metric on one side and inch/fractional on the other side instead of the conversion table.

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.
