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.

After making sure the guitar's neck is in perfect condition, this small easy-to-use tool will give you the perfect angle to your bridge. It's amazing how such a small change can help you improve your playability.

RADIUS GAUGES - MUST HAVE...!

These will help you maximize your guitar's playability. You can, and should, do this yourself - there will be plenty of things that will be beyond your ability that will need to go to your local professional repairman, but this you can do yourself.

Perfect Little Tools

I never knew how much these radius gauges would come in handy till I actually started using them. They are the perfect little tools for verifying fretboard radii, setting string action, and adjusting PU pole pieces. Buy these, and you WILL use them every time you set up a guitar; they give perfect results every time.

when you have a stack of guitars to setup, you'll have more time for other adjustments.

Understring Radius Gauge..

By DaVinci Luthiers from Oakville, Ontario, Canada
(Customer's Reviews) Wednesday, April 24, 2013


This is a very useful tool!!! I use this after the high/low 'E' string heights have been set, and then adjust the A,D,G,B strings accordingly... Fine tuning after the height and radius have been set is always a must... I would highly recomend this tool, especially if you are doing alot of set ups... Worth its weight in gold when used properly...

Excellent set. I had a set of the quasi cardboard gauges, but a few of them broke - these will last a lifetime...
