Full contact, precisely tapered
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."
Dan creates tapered shims that cover the entire heel of the neck. With these ready-made shims, that work is done for you. We've even lasered a line to make it easier to fit the shim in a pocket with a squared bottom.
"My Jazzmaster needed a better string break angle over the bridge. The 0.5-degree shim let me raise the bridge to the height I needed. And it fit the neck pocket perfectly."
