Keep these on hand for a quick turnaround on this common repair. 5. Set includes 3 hard maple shims in the following tapers: 0.25-degree taper, 0.5-degree taper and 1-degree taper. 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 you'll reach for most often – it works great on many guitars. 1-degree taper for guitars with a Tune-o-matic bridge.
