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.

As i do all my own set-ups etc, these gauges have taken away all the 'naked eye' problems and give me a much better and easier playing guitar

That's what your guitars will play like when you use these to adjust the radius and action...I have been needing these for years and now that I have them: they're not leaving the shop. My Custom Shop Strat has never played so well

Great Little Set

These have turned out to be a very helpful easy to use tool. I had no idea a 2nd hand neck I bought had such a huge radius unsuitable for playing or working on. That saved me a lot of time & money already. Brilliant!

The 9.5 gauge makes a setup on a strat an absolute pleasure. I dont know how I survived without it before.

Understring Radius Gauges

These gauges were the icing on the cake! Takes all the guessing out of setting up my guitars, especially the 7.25 radius on a few of my older strats! Money well spent....these gauges rock!

These are a must have for ABR bridges

By dsteiner from Mechanicsburg, PA

I use them to check the radius of the fret board and make sure the ABR bridge is the same. Surprisingly I have found many bridges that were off and needed filing. Great product.

this things last forever...made from light stainless steel, better from my old DIY duplex radius gauge; the stings eat them. really useful & accurate.

These gauges made setting up my guitar and bass so easy! And they play great now. Glad I got these gauges.

Secret Weapon

This is another one of those things I wish I knew about years ago. After messing around with Strats and Teles and trying to eyeball (or using the Braille method) them into being right, there's a tool that can do it in a matter of minutes. I switch a lot of necks for my road guitars and this is such a sweet addition to my kit. Keep innovating!
