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.

Not for 5 or 6 string Basses

nice tool, but it's too short for 5 and 6 string basses

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.

Seting the (Radius) to your strings,I could Never do it without these. This should be one of the first tools to buy. My guitar never felt easier to play, and they will last you a life time

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.

I love it

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!
