Details

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.

Set of 9 now includes new 17" radius for Ibanez guitars!

Find your fretboard radius, and set your bridge saddles to match. They're handy for matching pickup polepiece heights to the arc of the strings, too. Precision laser-cut from .050" stainless steel.

The set of 9 gauges includes:
7-1/4", 9-1/2", 10", 12", 14", 15", 16", 17" and 20" radii.

They'll work for string spreads and fingerboards up to 2-5/8" (66.68mm) wide.

I find these essential. They are far more versatile than any other type of radius gauges. Wouldn't be without them.

TROUBLE SHOOTER

By RF-GUITARS from Canada
(Customer's Reviews) Wednesday, March 05, 2014


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.

Fantastic!

Another use for that hole.I turn it into my multitool.

Size does matter...

By ElectricLarryLand from New Braunfels, Tx

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.
