check out vids of his live performances. he has a unique picking style. he doesn't anchor his hand and pick, at times he seems to be almost strumming. i wonder how he got such great individual note clarity when it looked like he was hitting all four strings at once.
at any rate he has a very animated right hand and this has always seemed to me to be the crux of his tone/style.
