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.

These are great!! They are easy to use and make setting string height a breeze. Used them first on my Telecaster and it now plays like a different guitar. My Strat is next.
Thanks Stewart-MacDonald for a great product.

Quick work

I was expecting these gauges to be of high quality, but was blown away by how solid they are! Real time saver and takes the guess work out of setting up a guitar bridge

Just what i was looking for.

I'm just a guitarist, not a luthier but i've been doing some repairs to my Strat and i got the haynes manual for Strats and saw these inside! Took forever to find them online but i found these and though i only really need the 9.5 one i couldn't be happier!!!

Almost perfect

Good tool, really useful. But why is it so short? I mean, you can't use it on a 7 strings guitar, nor a 5 or 6 string bass.
