Durable stainless steel!
Quickly find the curvature of a fingerboard or bridge with these sets of radius gauges.

Use them frequently to check your work as you smooth or shape a fingerboard or frets: a quick visual check keeps you from accidentally altering the shape — a mistake that's easy to make and hard to fix.

Sold individually or SAVE when you buy the set of all three radius gauges.

Guitars commonly have a "compound radius," meaning the curvature changes from the nut to the end of the fingerboard. "Eyeballing" this subtle change is next to impossible; that's why a set of radius gauges is essential. Also use them for profiling an acoustic bridge saddle and setting the string heights on an electric guitar bridge. Our gauges have precision laser-cut 7-1/4", 9-1/2", 10", 12", 14", 15", 16" and 20" radii. They're made of stainless steel for durability in the busy shop, and work for string spreads and fingerboards up to 3-1/4" (82.55mm) wide.

Use them in combination with our Radiused Leveling Blocks, for professional results.

New notched gauges work with strings on! This new version is handy when you want to check a fingerboard without taking the strings off. The set includes closely-spaced string notches for use near the nut, and wider spacing for use near the body (great for compound radius fingerboards). This set includes the same radii as our regular set.

I've used my set of these so much that the printing is coming off. They're great for a quick radius check even on guitars with a known radius. You never know what some shady luthier may have done to a fretboard's radius before you got it. They're awesome for setting bridge saddle radius and for "radiusing" pole pieces on humbucker pickups which I do on every setup.

Radius Gauges

Excellent quality gauges. Give me a very accurate reading of the fretboard. My only gripe is they're to big to fit across the bridge of my Telecaster. Need to trim the corners.

Essential for setups.

Makes short work of setups in congunction with the undersaddle radius gauges. Indispensable tools for setup work.

Excited to get these!

Had been eye-balling these gauges for the last 4 years - finally broke down and got them. Wished I gotten them sooner - I previously tried using my own homemade gauges off the Internet, but never could determine the correct radius of my fretboard (a cheap Fender Squier Start). Used a flashlight behind these and figured out I had a 12" radius. From that figure was able to set string heights over fretboard and pickups properly, and even managed to set the same radius on the saddles (standard Fender bridge). Note: I ended up using a small flashlight behind these gauges while testing for which radius was the correct one for the fretboard.
