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.

Radius Gauges

By Custom Saddles by Bob Colosi from St. Marys, GA
(Customer's Reviews) Wednesday, April 20, 2011

These are perfectly designed. A MUST for accurately creating and reproducing nuts and saddles.

Needs slots.

These are Ok but they really need slots. Go for the slotted type instead....I ended up slotting my own within 10 minutes of opening the package.

great if the strings are off...

A must in any repair shop

I love these radius gauges. Now I can see if there's a compound radius on the fretboard. Great tool to have.

A Winner

We all need these,well made and makes any job faster and easier

Would be better with one change...

By DM from NS
(Customer's Reviews) Tuesday, January 04, 2011

The earlier versions were plastic, and weren't as reflective when you put them on the strings, so they were easier to look at. Bring back those, and you've got a winner!
