Product Description

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.
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.

This handy set of 9 gauges includes all popular fingerboard radii. (7¼”, 9½”, 10″, 12″, 14″, 15″, 16″, 17″ and 20″).

They can be used to accurately measure fretboard radius, saddle radius nut radius from either the top or the bottom radius surface.

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