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 F*der and many other solidbody guitars.
1-degree taper for guitars with a Tune-o-matic bridge or Floyd Rose.
