well, the Flying V is a late 50's designheavy metal didn't even exist, and that look was associated with country music (like the Firebird/Thunderbird).
the Les Paul "is" a jazz guitar, designed by one of the greatest jazz guitarists of all time, that gave his name to it.
That's all true (though I had never really thought about the fact that the V was pre-metal, hehe), but those have been associated with hard rock and metal for so long.
Thinking about it now, that flying V was a pretty bold design! I imagine car culture may have influenced it? Even today it still looks pretty extreme (and probably why I associated it with heavy metal).
