Here's the video I had watch about a year ago:

I'm at work, so I can't watch it. He goes over his current rig, but as I recall, his rig is the same now as it was back "in the day".
I also found a you tube instructional video on playing the opening parts of Bridge of Sighs - a pretty cool blues riff. He definitely takes a minimalistic approach, but it is awesome in its simplicity!! Strip away the effects pedals, and it still sounds awesome!
