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.

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.

Very useful tool

Very useful little tool.
Might be even better with 2 sides graduated, 1 inches and 1 metric, instead of the table conversion not so practical.

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.

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.

Fantastic setup tool with a little drawback

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.

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.
