Suitable Size: The guitar neck shims are available in three angles (0.25, 0.5, and 1 degree). Each shim measures 55x75mm / 2.17x2.95 inches. The taper is 0.76–0.48mm / 0.03–0.02 inch for the 0.25-degree shim, 0.71–0.2mm / 0.03–0.008 inch for the 0.5-degree shim, and 1.52–0.25mm / 0.06–0.01 inch for the 1-degree shim.
