Guitar Neck Shims StewMac Preshaped, Pack Of 3

To change the angle of a bolt-on neck, players and repair shops have used shims for years.

StewMac created tapered shims that cover the entire heel of the neck. With these ready-made shims, that work is done for you. Making a quality shim takes time! Keep these on hand for a quick turnaround on this common repair.

There are 3 different degrees available for changing the pitch of a bolt-on neck. The 0.25-degree shim offers the most versatility. Stacking them will let you really dial in the neck angle you're after.

The 0.5-degree shim is the one you'll reach for most often. It works great on Fender™ and many other solid body guitars. 

The 1-degree shim is great for guitars like the JM and Jag that benefit from a setup with a steeper neck angle in order to increase string pressure on the bridge. Current ‘American Original’-reissues of these models actually feature a 1-degree angled neck pocket to negate the need for a shim but vintage guitars and earlier reissues from the USA, Mexico and Japan don’t have this feature.
