Understring Radius Gauges

About This Item

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.

Low profile fits tight spots. The slim shape of our understring gauges allow you to read the fretboard radius even with the strings on! This is also handy for matching pickup polepiece heights to the arc of the strings. And setting bridge saddles is easier than ever.

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

Standard width 6-string guitars and most 4-string basses—spans a string spread up to 2-5/8" (66.68mm).

Extra-wide covers string spreads up to 3-3/4" (95.25mm)—enough for 4-string, 5-string, and many 6-string basses. They'll also handle 7-string and 8-string guitars.

Stainless steel.

Fantastic Product!

Essential for any guitar tech! No reason to buy the radius gauges, these ones does it all. The only thing I'm missing, as with all radiused Stewmac products is one for the Ibanez 430mm radius.

Great tool

Well made tool with rounded edges and clearly labeled. Radius is the same on top and bottom so checking fingerboard radius, bridge radius, or under string radius are all a snap. Will have these as long as I work on my own equipment.

Invaluable tool

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.

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.
