Speaking of Warren DeMartini, Charvel has a Q&A with him posted on their site. I especially like the part about Warren and Jake E. Lee:

Imagine this: We’re both hanging out in the middle of the night watching a crappy TV with bad reception, sitting on the floor with our backs against the couch. I’m chipping away at the chords to “Round and Round,” and he’s chipping away at the chords to “Bark at the Moon.” We had no idea where those songs would take us.

Indeed.
