Set of 9 stainless steel gauges for fast, accurate bridge saddle adjustment. Not as nicely made as our more expensive understring gauges, but they do the job at a economic price.

Each of these unique gauges has a 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.

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 eight 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.
