Dude, one word : "ESP"
Those guitars are the fucking best, check out the Ltd custom series, i've played on one of those babies (gold and black) and they sound awesome.
Only sad fact is that Matt heafy is playing on them aswell =[
But yeah Alexi from CoB is endorsed with em, so is Roope Latvala and Hennka Blacksmith, i think.
And Abott from Arch Enemy, and some other dudes.
I already have an LTD Explorer (used it in 2 of those videos I posted, actually). I would love to get a black DV8 guitar at some point (best looking flying V guitar EVER).
But yes, Alexi Laiho has an ESP, Dave Mustaine HAD an ESP (he designed the DV8), Michael Amott from Arch Enemy, the guys from God Forbid, GWAR, etc. There are a lot of good artisits using their guitars.
Matt Heafy is using Dean (more specifially, the Razorback), & Dave Mustaine just signed with Dean & desgined a new V with them.
