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.

I like the compact design on the gauges. The hole in the handle was a nice touch too. Gauging beneath the strings between the pickups makes saddle adjustments so much easier and quicker.

I use mine for under string adjustment, "over string" adjustment, nut shaping, even pickup pole profiling. Also good to investigate and spot fake necks (most signature fenders are 9.5, and most gibsons 12"). I like to check fret seating too (a small flashlight and the corresponding gauge do the trick).

Very helpful gauges

Another item I put off buying in favor of making my own from online printouts, to bending a piece of wire to match the radius. These take all the hassle out, and showed me where I was off with my homemade gauges! Worth the price and very well made.

I am truly impressed with the ease of use of the Understring Radius Gauges. Up until that point, the action on my bass was too high and uneven across the neck. Now the action is low and silky smooth. A must have tool for ALL basses and guitars. Thanks again StewMac...

These are pretty cool, can check the radius both ways. I just wish I could have only bought the gauges for the radiuses I use.

I used these to set up My new Les Paul Standard and discovered that not all LP's have a 12" radius. Mine actually has a 17" radius. Takes all the guess work out of play instantly and it gives the confidence to set up any guitar that comes my way! I always wondered where I would get the tools I need to set up shop,now I know. Thank You for being there. Sincerely, Paul!
