String Radius Gauges

Lutherie tools. The width of the radii is 2 5/8" - suitable for 6-string instruments. Width of the bar is 0.21", making them suitable as under-string gauges, as well as for checking fretboard radii (the radius matches for both top and bottom). Sizes (9 pieces): -7.25" -9.5" -10" -12" -14" -15" -16" -17" -20" Material thickness is 0.75mm. Check out www.electricherald.com for more lutherie guides and resources.
