CHRIS SQUIRE (top photo)

As ’60s gave way to ’70s and rock music sought to fulfill its full artistic promise, progressive rock was born. The undisputed kings of this scene were the English group Yes. As one of the few prog bands that actually made hit singles, Yes brought a level of musicianship to the mainstream that’s rarely been equaled. Bassist/songwriter Chris Squire was the band’s driving force and one of the most influential players ever. For someone of his ability, a regular instrument just wouldn’t do. So he picked up this insane triple-neck Wal from Yes keyboardist Rick Wakeman. Though most players wouldn’t even know how to tune the thing, Squire regularly wrestled the beast into artful submission.

As if we needed further proof that Steve Vai is an alien. How can a human play two opposing guitar necks simultaneously? It just ain’t fair to us mortals (attention guitar nerds: we know that Michael Angelo Batio did this before Vai, but he’s an alien, too). Steve put a lot of miles on this crazy axe. He debuted it in David Lee Roth’s 1988 video “Just Like Paradise” and used it with both Whitesnake and G3. He autographed it at the Hard Rock in Orlando when he was appearing with Zappa Plays Zappa in ’07.
