Suitable Size: These guitar neck shims come in three angles (0.25, 0.5, and 1 degree). Each shim measures 55x75mm / 2.17x2.95 inches.

Function: These guitar neck shims are designed to adjust the angle at which the neck is secured, helping to achieve proper neck alignment without creating air pockets, thereby reducing the risk of damage to the instrument’s body and neck. Perfect Restoration: These shims serve as an effective tool for restoring or adjusting your bass or guitar. Their flexible wooden construction allows for light sanding or trimming to meet specific fitting requirements, providing protection when correcting neck angle issues.
