StewMac Standard Understring Radius Gauges, Set of 9

When to choose it
Choose this set when you maintain instruments with several fretboard or string radii. It includes intermediate values absent from the four-piece set, so check the exact radius on each instrument before deciding which set covers your work.
The listed span is 2⅝ inches. If the instrument uses a wider string array, compare the extra-wide variant, which changes reach even if the radius markings are similar.
