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.

Use it ALL the time

I have two of these, one I have in my tool box for guitar repairs (for customers). The other is in my gig bag, just in case I need to do a quick setup for myself or one of my band mates.
I think this is one of the MOST used tools I own (besides a string winder).

Perfection Attained!

I bought a new Alembic bass in February & fought it for 6 weeks trying to get the action low with no buzz, then I bought the String Action Gauge from StewMac & within 10 minutes I had the action perfect! I had been measuring wrong with a ruler for 6 weeks! I was ready to drive to Dallas to have my bass set up by a pro, but now I don't need to! This tool is a must for anyone who works on their own guitar or bass!

Excellent Tool

For years I spent time trying to get the proper distance from the strings to the frets. I never was able to do it without having my eyes roll back in my head while I stared for hours. With this tool I was done in less than 10 minutes without eye strain or pushing or holding frets. I should have bought one of these years ago.

I'm impressed!!!

Wow, it has a lot of options.
Very accurate, I thought my Taylor 412CE sounds OK....I needed some practice but I was surprised about the difference, a lot better!

Amazing tool!

When I saw the pictures I thought it was just silk screened onto the steel, but when I got it I saw that it's actually sunk into the steel! amazing detail and extremely accurate, will last a lifetime

It helps

I haven't used this in every place that I will, but checking the string height or the neck straightness on the 8th fret is still more difficult than reading one of the digital caliper.

String Action Gauge a worksaver !

This little multi purpose ruler is just what the doctor ordered for bass and guitar setups. A real timesaver that rests on the frets for more accurate measurements. Well worth the money.

String action gauge

How can anyone truly measure action without one of these? Buzzing? You'd be lost without one.

Like everything I've purchased from StewMac, this gauge is precise and high quality.
