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.

TROUBLE SHOOTER

These saved me from an error I found on a neck said to be 12" radius. It had a 16" instead while the frets were at 12". Bought the 16" radius sanding block and self adhesive 320 grit/paper and voila, problem solved. Also great for radius' on Gibson saddles, if you have a high/low spot and need to re-slot each saddle.

Size does matter...

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.
