Package Content: You will receive 3 pieces of guitar neck shims made of solid maple wood, offering greater resonance and stability compared to plastic, helping maintain the natural sound of your guitar or bass. 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. Function: These guitar neck shims are designed to adjust the angle at which the neck is secured, providing a secure fit. The shims allow precise tilting of the guitar neck without creating air pockets, helping prevent wear and damage to the instrument's body and neck. Perfect Restoration: These shims serve as an effective restoration tool for guitars or basses. Their flexible design allows for cutting or sanding to achieve a custom fit, helping protect your instrument from damage due to improper neck angle.
