According to a posting on the MEGADETH fan site Rattlehead HQ, it is strongly rumored that MEGADETH mainman Dave Mustaine is no longer officially endorsed by ESP Guitars. Currently this has not been officially confirmed by ESP or MEGADETH, but according to a posting by an ESP dealer on the MEGADETH forums, ESP has been instructed to sell the last of the DV and Axxion Mustaine signature lines of guitars. Some have speculated a return for Dave Mustaine to Jackson Guitars. "Rayna" of the MEGADETH forums has posted the following:
"The [Dave Mustaine Jackson return] is rumor, and nobody really knows anything other than ESP and Dave have parted ways, contrary to what everyone seems to think they know. There is the chance that maybe he'll stay and take the deal with fewer free guitars. It's an equal chance that he will go elsewhere.
"As a personal issue, it just didn't work out. Maybe Dave will speak up and finally tell his side, but nobody at ESP is badmouthing him. He will always be an icon, no matter what he plays…
"The only real fact and the one with evidence, is that as of now, Dave and ESP are no longer in business together… There are a total of 2 black DV8s (ESPs) coming from Japan, and that's it. The production is done, the Axxions and DVs are all made and out there. There's not even any backstock to replace defective ones.
"Add to that, ESP gave all its dealers the okay to whore them out and get the line over with…"
Further to this, Dave Mustaine and his signature guitars have been removed from the Japanese ESP web site.
