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 Bolt-On 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.

These shaped shims fit most neck pockets with a rounded heel. You can trim along the lasered line to fit the shim to a pocket with a flat heel, like a Tele.

This set includes 3 hard maple shims, each at a different taper for changing the pitch of any bolt-on neck:

  • 0.25-degree shim offers the most versatility – stacking them will let you really dial in the neck angle you're after.
  • 0.5-degree taper is the one you'll reach for most often – it works great on Fender and many other solidbody guitars.
  • 1-degree taper for guitars with a Tune-o-matic bridge or Floyd Rose.
