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.

Wow, these understring radius gauges are great! No more guessing, bang on bridge AND pup adjustments! Setup my Strat, 330/Rickenbacker AND my 5122 Gretsch. Thanks for the fast and courteous delivery too.

I have always went to a music store to have my guitars set up, because I didn't have the proper tools. Stew Mac has now allowed me to afford my own tools and do my own work, by myself. I set up a 1985 Strat by following on line instructions and experimenting with the guitar and tools for about an hour. I am happy and pleased with my purchase from Stew Mac and would suggest any guitar player who is getting into building get a set of gauges for them selves. Jim Nash
