Dave Mustaine's personal ultra-rare prototype Jackson Y2KV (J6443) is set to be listed for auction at Megadeth's official eBay store in mid-January. This natural unfinished Jackson prototype with a special branded Jackson logo on the headstock, was designed by Dave Mustaine and presented to him on 12/23/1998, and featured on several magazine covers including Guitar Magazine in 1999. This was the first guitar with the final 3+3 Y2KV head, but with dot inlays, rosewood fingerboard, alternate knobs and a blade switch. The body shape was not quite finalized either, but this was the first approved prototype, used by Dave Mustaine as reference for the final prototype. Stay tuned for more details and keep checking back to the Megadeth eBay store.
