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.

One of the most used tools on the bench

Invaluable for setting action heights, measuring fret slot depth, etc. Stays on a magnetic tool holder strip right above the bench because I use it frequently.

A must have

This tool is a must have in order to check your own sting action. Combined with the Radius Gauges, performance is improved amazingly.

Every guitarist should have one of these..!!!

These will help you maximize your guitar's playability. You can, and should, do this yourself - there will be plenty of things that will be beyond your ability that will need to go to your local professional repairman, but this you can do yourself.

String Action Gauge - a MUST!

As an amateur "modder", this has been a gift of a tool for me. It is precise, extremely useful in many circumstances, and fairly priced. My only wish would be that it was made from a thicker gauge steel so as to act as a reliable straight-edge.

Must have item

If you do any of your own setup, you must own one of these. You'll wonder why you didn't buy one years ago.

String Action Guage

Amazed how handy this gauge is to have around. Already used it on my guitars, mandolin, ukuleles, violin, mountain dulcimer, and just today on a psaltery that I am refurbishing. So much easier to use and read than a conventional ruler. If I ever lose this one, I would have to buy another.

Must-have for setups

This tool makes action adjustment a breeze. Another tool I buy multiples of and give away as gifts. I have both the standard and metric versions.

Want accurate string action?

This is the best measuring tool for setting your string action. Sits across a few frets to avoid rocking. A must have tool.

The One Ruler to Rule them All.

All jokes aside this ruler is a must have for every Luthier or Tech. There are endless uses for this in the shop. Pull the trigger and you wont regret buying this. This is my most used tool in the shop.
