This is from the first shipment, so we're offering it at a slightly lower price. The price will likely increase slightly in the future. Please take advantage of this opportunity. This is an aftermarket product imported from overseas. The design of this backplate changes frequently depending on the manufacturing year, but this is a replica of the one included with the Historic Collection models released in recent years. It is not an original. Since it is not sold separately, please take this opportunity. Color: Silver Diameter: 54mm Thickness: 3mm (outer edge) Material: Metal Mounting screws are included. These are the screws used to secure the truss rod cover on guitars like the Flying V, and they fit perfectly for the back panel. We can accommodate color requests (chrome, black, gold). If you already have the original screws, please use those.
