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.

String Action Gauge

While not a luthier, I do want to be able to assess a guitar's action, fretboard condition and setup characteristics, whether I'm buying a guitar or maintaining my own. This is a great tool that provides a quick, accurate measurement of string height. It's a must-have tool in my shop.
My recommendation for taking it to the next level - reproduce the scale in reverse order on the opposite edge or on the back so the gauge can be used from both sides of the neck and you can measure the high-E string at the first fret without looking through 5 strings.

String gauge

I've used rulers for years to set string height with so so results. The string gauge takes all the guess work out of setups. I should have bought one of these years ago.

Wow! Best $$ spent on my guitars.

If you only own one specialty tool for your guitar(s), this should be it! I use it for not only setting string height but for adjusting the bridge, measuring saddle width, pole adjustments, etc. Anywhere on your guitar that a small accurate measurement is needed, this tool has you covered. Great product!

Great tool

I've used everything from business cards to my wife's quilting ruler. Finally I know exactly what the height is. Looks great too.
