This item is a very limited Custom Engraved Neck Plate, made to commemorate one of the greatest musicians of all time, Buddy Holly. This can be a great addition to your project guitar. The graphic was applied using a Photo Impact Process where the metal is actually etched, leaving a permanent, almost holographic image. Dimensions are the traditional size found on most standard 4-Screw Bolt-On Joints ("Fender Spec"), but please measure your particular guitar to be sure it will fit correctly. They are available in Chrome or Gold.
