As something of a guitar nut, I'll point out something wrong with your story. The Gibson Flying-V, while now traditionally assosciated with metal, was originaly introduced into Gibson production in 1958 as a new, strangely shaped guitar, along with its equally metallic brother, the Gibson Explorer. However, initial reception of the guitar was tepid at best, and only a few copies of each were made before the Gibson factories shut down production of those models. The first people to actually use these unpopular guitars were Dave Davies of the Kinks (Flying-V), and one of the guitarists from Lynyrd Skynyrd (Explorer), neither of which can be remotely described as "metal".
