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.

Understring radius gauges, 5 stars!!!

I bought these for my shop after using the older, big square radius gauges. I had to order a bunch of supplies for my shop so I decided to get these as they looked like a great product. They are. They get used on every job and are so easy to use above and below the strings. I highly, highly recommend them.

excellent tools

I found the radius gauges to be really helpful especially for setting up my guitars.Which is what I use them for the most.

Great idea

Useful, simple, multi-function and inexpensive. They never had stuff like this when I started playing 45 years ago. I can think of about half-dozen different uses for these, all related to correctly matching radii with regard to action, nut-making, saddles, slots, etc. Well worth the money and eliminates guesswork.

Used these gauges to set up my Fender Strat Vintage and AM Deluxe and it made the job so easy. A really good piece of kit to have around.

For Bass 5 ?

Excellent but I'd like to have a system that works with 5 strings bass... Neither the width or the hand support (in the center of gauge)fits the needs of 5 string basses! Understring radius setting on bass is very important for bass(...more than guitar) and specially on 5 or 6 strings! Cheers,

great

I don't rely on these for every setup I do but they come in handy often enough to be glad I own them.

Incredible gauge!

Wished I'd gotten this set of gauges sooner. Like other reviews here, it was taking a lot longer to set radius of saddles with other tools. Used these gauges with the overstring radius gauges and got a perfect setup the first time I used them. The overstring gauges are great of course, but these helped me fine-tune a heck of a lot better. When I finished the radius of the saddles and strings were about as perfect as I could get them. Quite happy with these!

great!!!! tool
