Details

Fast, accurate measurements for setups. Our String Action Gauge is a "Swiss Army Ruler" for setup adjustments on any stringed instrument.

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.

This is a great tool to have around. I have several guitars that all feel a little different, a good thing in some cases but in others not so much. Forgive me for wanting both my SG's to feel alike. Enter the string action gauge. The slight different in string height is no longer an issue.

A high quality, practical rule. Use the horizontal string guide to hone in on relative height, and the 1/64" for more accuracy.

I like so many others was using a six inch steel rule. Now that I have the String Action Gauge set up of stringed instruments is much easier.

I've been using a small 6 inch steel rule to measure string height. What a pain. This little gauge though quickly and accurately lets me find the correct height of the strings. Plus many other uses. I even use it to set up my band saw and router.

Love it should have purchased the standard version instead of the metric version because all my guitars are made in USA.

So used to using just a regular 6 inch scale for set up measurements. I am still finding myself to be forced to use this little guy. I think in the sweet spot area, say .050 - .070 there should be .005 incriments.
