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.

The set of 9 gauges includes:
7-1/4", 9-1/2", 10", 12", 14", 15", 16", 17" and 20" radii.

Standard width 6-string guitars and most 4-string basses—spans a string spread 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.

Stainless steel.

Nice, simple, appropriate gauges...

There ought to be a single tool that adjusts on the fly for this task. Further, at the price, I wish these were a little more substantial- I feel they might torque or bend if handled a little heavier than normal or they get dropped and stepped on. I know... you're not supposed to be tough on them, but I just don't get the impression these are built to last.

Understring  guages and string action guage.

I always do my own setups, have for years, did them with just a ruler and tuner, but I just bought the under string guages and string action guide and boy do they make things easier. I just did ten electric guitars,with various radius and scale lengths,
I did strata, teles, Les Paul's and PRS and these tools make it so easy to get very buttery setups for each guitar. The radius guages help set the proper curve for the strings and the string action guage allows you to accurately match your setups from guitar to guitar even with different curvatures. I'm impressed !
Great tools !

Radius gauges helpful for bass guitar

By

Verified Buyer


I previously bought the set of S-M's earlier under-string radius gauges made of plastic for use on my 6-string guitars, but ran up the creek when I tried to use them on my 5-string Fender bass. This set made of metal is very nice and carefully made and is really helpful for bass guitars and 7- and 8-string guitars with their extra widths. The metal version isn't "better" than the earlier plastic set, though, as I've had no trouble with the plastic version. But it certainly makes intonating a bass much less frustrating.

They Do Help In Giving You A Better "Guideline" To Go By During Setup! Very Helpful & Saves Time Too!

I am enjoying these radius tools. I give them five stars really, but my only wish is that they came on some sort of ring so that they don't have to be either kept in a bag or risk losing one. I put mine on an over-sized keyring, but it would be really nice if this was standard for them. As for the tool itself, they do exactly what they say they do, and they're accurate!
