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.

Standard width covers 6-string guitars and most 4-string basses—the gauges span string spreads 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.

Available in three sets to fit your needs:
Standard width, set of 4 includes these common radii:
7-1/4", 9-1/2", 12", and 16"

Standard width, set of 9 includes these radii:
7-1/4", 9-1/2", 10", 12", 14", 15", 16", 17" and 20"

Extra-wide, set of 9 includes these radii:
7-1/4", 9-1/2", 10", 12", 14", 15", 16", 17" and 20"

Stainless steel.

Get a solid baseline with these gauges

By

Verified Buyer


Great way to get started on setting your action and during setup. Doesn't get much easier to use, and gives you a solid baseline for starting you action setup. Once the string height is established with the curve of the fretboard radius, then you can move onto intonating properly.

I ordered these gauges to check the radius on my guitar's . I have both electric and acoustics and they worked great. Now I have made some fine adjustments and I am confident my setups are correct. Very easy to use.

Great tool, shame no 11 inch.

Great tools, big shame that 11 inch measurement is not represented. Was hoping to use these for my stingray basses which are 11 inch. For such a common and popular bass, it is disappointing the measurement is not made nor was a custom order made available by stewmac.

These were perfect for what I needed. The video was very helpful showing the different types.
without the video I probably would have ordered the wrong type for what I wanted to do. Since I have a variety of guitars I needed most all of the sizes. Great service and a great product. Thank you.
