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.

A gauged success

A great set of gauges to check string heights are aligned to the fretboard radius which I note for ever guitar I setup. I am not a luthier, just an enthusiastic amateur. I like to do my own setups as the difference it makes to the playability of any guitar is huge. Anything that makes the job easier and more precise is appreciated.

These are great for when a customer comes in and says they have a certain radius and swear by it. In just a few seconds you can show them what's really up not only with their fret radius but you can also easily check to see if their saddle radius has been set correctly.

It took just a few minutes to set up the bridge with the understring radius gauges. I just needed to tweak a few things to adjust to my particular neck and I was playing in under 15 minutes. These gauges are a must for anyone seriously building guitars.
