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.

VERY handy tool, but why does it cost $19?

If you "mess around" with guitars at all, this tool is very, very handy, no question about it. But I do not understand the price. Were it plastic, I would expect it to be given away at guitar shows. Being metal ups the price some but THAT much? Even so, why does one have to buy two if you need English and Metric scales - why are they not on opposite sides. Don't get me wrong - I like it and use it often but the price seems quite high for what it is.

Usually stew mac tools are second to none.

This item gets the job done, but I've got to say, the build quality is fair at best. Unlike the shiny, silvery to almost whitish metal shown in the photos on this page, the gauge I received is very dark metal, making the almost equally dark printed markings on the gauge very difficult to read even under my bright, workshop lighting.

In my attached photo you can see my new, just removed from the Stew Mac packaging, action gauge side by side with an two year old, $10 aluminum architectural scale.

I think the photo pretty much speaks for itself.

Awesome tool

If you thought you were measuring accurately - think again. This made my setups improve a lot as I finally was getting very precise measurements. Get one of these. Small changes make a huge difference and this really identifies where issues are.

a REALLY neat, precise way to measure string height over the frets, that is a LOT easier & faster than measuring the same with a micrometer.

How did I get by without it?

This is a great tool. I had to get one for the work bench and one to carry with me as there are so many uses for it!
