Understring Radius Gauges

About This Item

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.

Low profile fits tight spots. The slim shape of our understring gauges allow you to read the fretboard radius even with the strings on! This is also handy for matching pickup polepiece heights to the arc of the strings. And setting bridge saddles is easier than ever.

The set of 9 gauges includes:
7-1/4", 9-1/2", 10", 12", 14", 15", 16", 17" and 20" radii.

Standard width 6-string guitars and most 4-string basses—spans a string spread up to 2-5/8" (66.68mm).

Extra-wide covers string spreads up to 3-3/4" (95.25mm)—enough for 4-string, 5-string, and many 6-string basses. They'll also handle 7-string and 8-string guitars.

Stainless steel.

Surely everybody has a set of these to go with the radius blocks? This is a no brainer.

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.

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

Verified Buyer


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.
