<span style="vertical-align: inherit;"><span style="vertical-align: inherit;">To change the angle of a bolt-on neck, players and repair shops have used shims for years. <br><br>All kinds of materials have been used, from matchbook covers to guitar picks stuck in neck joints. In the early days Fender™ used shims for factory setup work as well, particularly for JM and Jag models. At first a synthetic rubber strip was used, from the mid-sixties a material similar to thin cardboard / sandpaper appeared. These 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."<br><br>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.<br><br>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.<br>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.<br><br>Taper specs (approximate):<br>0.25-degree shim tapers from 0.030" to 0.019" (0.76mm to 0.48mm)<br>0.5-degree shim tapers from 0.028" to 0.008" (0.71mm to 0.20mm)<br>1-degree shim tapers from 0.060" to 0.010" (1.52mm to 0.25mm)<br>Dimensions: 2-3/16" x 3" (55.56mm x 76.12mm)<br><br>These shims fit most Fender™ 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 TL.<br>Made of solid maple to match the guitar neck.<br><br></span></span>
