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.

Use the 16" gauge to set up my saddles and nuts as well as checking the radius on finger boards. Would be lost without it!

Useful for checking any radius you could need to check, from fretboard curvature, to saddle setup, and even nuts if you are creative.

Have to be one of the easiest way to set up the correct radius. Just set both the 1st & 6th strings to the height you want and then tweak! the radius to match. Your setup complete within a minute :-)

These are exactly as they are described. They are heavy enough that they don't seem to be likely to bend. Good product.
