Package Content: You will receive 9 pieces of guitar neck shims made of solid maple wood, offering greater resonance and stability compared to plastic, helping to 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), with each shim measuring 55x75mm / 2.17x2.95 inches. Function: These guitar neck shims are designed to adjust the angle at which the neck is secured, allowing precise tilting of the guitar neck without creating air pockets. This helps prevent wear and damage to the body and neck of your instrument. Perfect Restoration: These shims serve as an ideal tool for restoring your bass or guitar. Their flexible design allows you to cut or sand them to fit your specific requirements, providing protection against damage caused by incorrect neck angle positioning.
