MEGADETH mainman Dave Mustaine's personal ultra-rare prototype Jackson Y2KV (J6443) will be listed for auction at the band's official eBay store starting Thursday evening, January 10. This natural unfinished Jackson prototype with a special branded Jackson logo on the headstock was designed by Mustaine and presented to him on December 23, 1998 and was 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 Mustaine as reference for the final prototype.MEGADETH recently resumed work on its fourteenth studio album with producer Johnny K (full name: John Karkazis), who has previously worked with DISTURBED, SEVENDUST, MACHINE HEAD and STAIND. The CD is currently being recorded at Mustaine's Vic's Garage studio in San Marcos, California for an early 2013 release via an as-yet-undisclosed label following the band's recent split with Roadrunner Records.
