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.

Excellent Quality

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.

Why did I wait so long?

These little beauties are an absolute treat - they've saved me so much time already and they help me produce a better setup every time. So much easier than fighting with the ruler! And being such a reasonable price, I wonder why I didn't get them earlier!

A must for proper set-ups

These gauges are easy to use and make set ups more refined. I highly recommend these!!

Pour un réglage parfait!

Ce petit instrument permet d'identifier la courbure de la touche et de régler parfaitement la hauteur des cordes. Tout simplement indispensable !

Radius Gauges

When selling guitars people often ask the neck radius. It seems to be very important to them. With these you can tell in an instant. I measure at the 12th fret. Very precise.

Radius gauges

I was having a hard time with the B string on my Lavavee acoustic occasionally buzzing from not seating on the fret with certain bar chords. The under string radius gauge showed that the saddle for the B string sat several thousands on an inch proud to the other strings. A slight adjustment to the saddle corrected this and now the guitar plays like a champ!
