Details

Fast, accurate bridge saddle adjustment.
Each of these unique gauges has an accurately radiused arc on both the top and bottom surfaces, and is shaped to fit easily under the strings.

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.

Makes for fast and accurate setups every time,another must have tool from StewMac

Invaluable tool

By Michael Myers from Maryville TN

I received these and immediately set about working on my Tele's and my Strat. Up until this point, I had always just "sight set" the radius on my Fender necks. I can't believe how much better my guitars play now and how simple it was to use these gauges. These are not the cheap plastic kind that will tear up easily, but are well designed metal and should last for years to come.


All of the guitar setup tools that I have bought from Stew-Mac have been top notch and have always improved the way that my guitars play and feel. Great playing guitars are where we guitarists love to live and Stew-Mac has the tools to make that possible.

I use it everyday and it¦s really easy to use. The same tool for checking the radius on the frets and setting the correct radius on the saddles. Sweet!

good for what it is

Have only used it a few times, but seems to be good. Have nothing to compare it with however. I believe if you have a need, it is worth the purchase.

Wow, these understring radius gauges are great! No more guessing, bang on bridge AND pup adjustments! Setup my Strat, 330/Rickenbacker AND my 5122 Gretsch. Thanks for the fast and courteous delivery too.

Ingeniously simple, this tool is a money maker for any tech. They almost take the thought out of setting bridge action. These help you do better work, faster.

You should own these

If you own a guitar, then these should be in your toolbox. They work so quickly, it's like cheating
