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.

GREAT TO HAVE!

I had never used these before to do a setup on my guitars and basses. I finally broke down and bought a set of these and I have to say that using these is precisely what I have been missing from my setups. Using these gets you just that much closer to perfection. I wish I had bought a set years ago! Great to have!

I just ordered my new set of Extra-Wide radius gauges today. I have two sets of the standard ones, an old plastic set, and a newer metal one. But what I REALLY love is that you people LISTEN to us guitar techs out there. I think it was just short of a year ago that I dropped you a line suggesting this product, and VOILA! Here it is! You guys AND your tools are the best! Happy to be part of the "family" for so many years, and thank you.

They are a necessary tool.
Nice set of gauges.
Only thing is they're a bit pricey or would have gotten 5 stars.
Thanks again Stew-Mac!

Amazing crafted quality! Very accurate in measurements! Helped solved so many unanswered questions I had regarding proper nut shaping and fitting, bridge saddles set-up, string to fretboard alignment, etc... Extremely useful and handy, especially with the ability to measure string radius and alignment going UNDER the strings!
Definitely recommend!

Every stringed musician should have a set

I have been playing guitar for twenty years on and off the stage professionally. What I never understood was that my guitars were always at a different radius at my bridge than the fretboard radius due to simple neglect. I have found that there are a lot of professional players out there who ignore these simple setup techniques and the difference is noticeable live on stage and on recordings. I certainly will never be making this mistake again on stage or in the studio now that I have my set. All of my guitars are getting this treatment from now on.

Also I really like the ability to store them on your keychain!

Checking the saddle alignment was so easy. When I was shopping I saw a cheaper set, but that's exactly what they were, "a cheap set". The StewMac guages were high quality and have helped me from the first day they arrived. You can also use these to measure the neck, but I'm going to order the square radius guage set to make reading the neck quicker and more accurate.
Thanks StewMac!

P.S. StewMac's customer service is the best I've seen...in any industry. Great - Prompt responses pre and post-sale!

A well needed, affordable addition to the bench. I don't know how I managed to get along without them. They have simplified a process that took me three times as long.

They were just as advertised I'm very happy with them and would suggest any one wanting to do any work on their own guitar to get a set.
