Neck Shim for Bass Guitar 0.25 Degree
Tapered maple shims used to change the angle of a bolt-on neck.
To change the angle of a bolt-on neck, players and repair shops have used shims for years. We've seen everything from matchbook covers to guitar picks stuck in neck joints.
Those kinds of shims create an unwanted gap under the heel of the neck: a dead air space where humidity condenses to swell the wood. As Dan Erlewine describes in his Guitar Player Repair Guide: "This gap may cause an upward kink in the neck. And many players feel they lose tone unless firm contact is maintained between the neck and the body."
Tapered shims that cover the entire heel of the neck—with these ready-made shims, that work is done for you. Attention, repair shops: making a quality shim takes time! Keep these on hand for a quick turnaround on this common repair.
