I spoke to Misha while he was there, he had been up for about 48 hours straight by the time they started filming. The session was pretty much a continuous 3 hour shoot, because they were strapped for time and needed to film the full 6 month's worth of his column in one go. It's a shame, because he's not camera shy and under normal circumstances is a very articulate speaker. Also, the weird gating effect GW use on the speaking doesn't do any favours to the perceived fluidity of the speech. It always sounds very bizarre on all of their videos...
The pickups are a Rebel Yell/VHII set. The covers were the battleworn black ones, but the neck cover has got quite a lot more weathered due to his very aggressive right hand technique causing the strings to hit the pickup.
