The Chetboard

I was excited to get the new Crossroads 2010 DVD partly because Earl appears and does some real fine playing. Since he was at CAAS 2010 which I missed, I wonder if any of you know how he amplifies his fine guitar - pickups, mic ? Certainly on the Crossroads show he has some electronics hanging off the back end of the guitar but you can't tell what it is. Wonderful sound - best amplification of a classical I've ever heard. Does anyone have a tab for Angelina or Vonetta ? - the two songs on that show. Incredible drummer also. I love the you tubes of Chet with Earl. Very warm. - Simon
