Understring Radius Gauges

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.

They'll work for string spreads and fingerboards up to 2-5/8" (66.68mm) wide.

Understring Radius Guage

By
(Customer's Reviews)


I seemed to always have problems with proper set-up and action on my guitars and wasn't willing to pay someone to do something that looked achievable. I already have the String Action Gauge and use it frequently-it's a necessary tool. I thought that to really milk the last drop when setting up, these under string gauges would help and they do. I needed some Stew-Mac wisdom to see if I was understanding how to best use these and their speedy response certainly helped. These gauges are a blessing to determine fretboard radius and somewhat helpful with string/bridge set-up especially with adjustable bridges like Fender's. I still rely on the String Action Gauge first and the feel of the neck while playing. I think these gauges are top quality and an added help when doing set-ups and I don't regret buying them. They lost a star because I think it would be helpful to include some written instructions to help us novices maximize our efforts or understand the limitations of these tools.

From the start I thought I would have to buy more radius gauges. But when I opened the package to see that the set included all the radius's I would need. I was happy with the purchase I made. You do need to have good lighting to make full use of these gauges. As you do with any precision tool. But in all the was a purchase well worth the money.
