Dave Mustaine is leaving Dean. This is his final week with the manufacturer & he managed to confirm this in a reply to someone in cyberspace. Rumour has it that he will be in the Gibson camp come 2021. There's a pic going round of the prototype, purportedly by a Gibson employee & he nearly got fired for it. I think Mustaine will be happy with whichever company that entertains his quirks.
