24 K Gold Plated.
The V.BLOCK is a complete SCREW-LESS system that includes the DTB and HPA.
It uses a 1/2 in. thick block mounted to the hinge-plate of the Bigsby B3 tailpiece creating distance between the spring cup of the tailpiece and the stud on Les Paul guitar bodies ONLY.
The hinge-plate adapter is designed to go on the outside of the B3 hinge-plate to raise the strap button out of the slot for easier access.
