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.

Imperative tool for any guitar player.

I've setup my guitars for years by sight and feel. I just didn't know any better. Recently bought these gauges when my new Strat was being difficult. WOW! I had no idea it could be so easy. 5 minutes of work with these and it played like butter. I'll never be without them again.

A welcome addition to the guitar setup toolkit

I used these to help troubleshoot a fret problem on a Sigma 12-string guitar. They will come in handy when I adjust my Gibson and Fender guitars.

Good Tool for accurate setups.

This tool has really sped up the setup for me! I simply set the top and bottom strings to the desired hight at 12th fret and lower the rest of the strings down to the gauge. Intonate and your done! Fast, simple and accurate.

Necessary Tool for Bridge Alignment!

With this tool, you can dial in the exact radius of your fretboard on your string saddles. Makes for easy (and even) string height adjustments.

Nice, simple, appropriate gauges...

By

Verified Buyer


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.

By

Verified Buyer


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 !
