Use the bottom curvature to determine your fretboard radius, and the matching top curvature becomes a reference for setting string saddle heights for best playability.

Set of 9 now includes new 17" radius for Ibanez guitars!

Find your fretboard radius, and set your bridge saddles to match. They're handy for matching pickup polepiece heights to the arc of the strings, too. Precision laser-cut from .050" stainless steel.

The set of 9 gauges includes:
7-1/4", 9-1/2", 10", 12", 14", 15", 16", 17" and 20" radii.

They'll work for string spreads and fingerboards up to 2-5/8" (66.68mm) wide.

The best radius guages

I find these essential. They are far more versatile than any other type of radius gauges. Wouldn't be without them.

These saved me from an error I found on a neck said to be 12" radius. It had a 16" instead while the frets were at 12". Bought the 16" radius sanding block and self adhesive 320 grit/paper and voilĂ , problem solved. Also great for radius' on Gibson saddles, if you have a high/low spot and need to re-slot each saddle.

Size does matter...

I like the compact design on the gauges. The hole in the handle was a nice touch too. Gauging beneath the strings between the pickups makes saddle adjustments so much easier and quicker.

Multi use tool

I use mine for under string adjustment, "over string" adjustment, nut shaping, even pickup pole profiling. Also good to investigate and spot fake necks (most signature fenders are 9.5, and most gibsons 12"). I like to check fret seating too (a small flashlight and the corresponding gauge do the trick).

Very helpful gauges

Another item I put off buying in favor of making my own from online printouts, to bending a piece of wire to match the radius. These take all the hassle out, and showed me where I was off with my homemade gauges! Worth the price and very well made.

Smooth Sailing

I am truly impressed with the ease of use of the Understring Radius Gauges. Up until that point, the action on my bass was too high and uneven across the neck. Now the action is low and silky smooth. A must have tool for ALL basses and guitars. Thanks again StewMac...
