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 preserve the natural sound of your guitar or bass. Suitable Size: The guitar neck shims come in three angles (0.25, 0.5, and 1 degree). Each shim measures 55x75mm / 2.17x2.95 inches. The taper is 0.760.48mm / 0.030.02 inch for the 0.25-degree shim, 0.710.2mm / 0.030.008 inch for the 0.5-degree shim, and 1.520.25mm / 0.060.01 inch for the 1-degree shim. Function: These guitar neck shims are designed to adjust the angle at which the neck is secured, allowing precise tilting without creating air pockets. This helps prevent wear and damage to the instrument's body and neck. Perfect Restoration: These shims serve as an effective restoration tool for guitars and basses. Their flexible design allows for cutting or sanding to meet specific requirements, providing protection against damage caused by improper neck angle alignment.
