Backstage at Madison Square Garden, after the show. He's very gracious and soft spoken. It's really fun to meet him, he's kind of taken on to me what was Garcia's sort of guru persona with the Dead. There's no rock star vibe around him, he's pretty humble, he gives you a deep nod, almost like a little bow, when he says hello and shakes your hand, and listens intently to what you are saying.
They did Fire on the Mountain that night in the second set, and Weir's guitar was extremely bright yet curiously thick, too ... really cut through playing those single-note FOTM riffs, almost like a keyboard would sound. He played his ES for the first set, but switched to a Strat for the second set.
Didn't talk a lot of gear with him, but my buddy Steve told him his guitar was so bright on Fire on the Mountain that it made his teeth hurt; Bobby just grinned and allowed that it doesn't sound too bright to him because his ears are pretty much shot for the high frequencies (perhaps another reason why he listens attentively). He also said on that tune, he used an octave divider with a note an octave up and another an octave down, plus an envelope filter. Very distinctive sound.
