Nice clip. I quite enjoy the mixes of playing style and tone style. That's actually the idea behind one of the songs I am (desperately) trying to put together, but I haven't been playing much lately.
I think guitars were meant to be tuned in C. I tuned my epiphone LP in open C (like Soundgarden did on some of the songs on their last album: Burden in my hand and Pretty noose). I am no metal guy as far as my playing is concerned, but still, the growls you get out of a Les Paul tuned in C are just where it is at, IMO.
And P90s are so cool. I have only one in the neck of my Studio, but I have never loved a neck pick-up as much as the MQ.
