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.

It was time!

When I brought one of my Strats in to get checked out, my luthier told me I set up my bridge and strings to a near perfect 12" radius. The problem is my board has a 9.5" radius. Bought the gauges, their precision is readily apparent, and fine tuned nearly all of my guitars. On new setups, they significantly reduce time. Don't know why I waited so long to purchase them.

Pretty sweet, great quality

I am just starting to fix and set up guitars and I am aware it takes the correct tools to do so. These gauges are a must. I'll eventually slap em on a key ring so I don't lose one. Due to the thickness of the tool, if the action is low enough on a particular guitar you won't be able to get up toward the string nut without scratching the fretboard... But I feel if they were thinner they would bend overtime.

I'm just a hobby player and guitar guy, working on my own stuff. This nifty little set helped me the most with setting up my vintage style tremolo saddles. If you like to save a few bucks working on your own stuff to get it the way you like it, not just the standard "set-up" these are worth their weight in gold. Get some and get your guitar feeling the way you want it too.

The only radius not present in this set is one that is completely flat such as found on classical guitars. I highly suggest these fantastic tools.
