Product 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.

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.

Awesome!

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.
