I dunno, that video quality was so bad; I can’t imagine him needing an SVT, in fact whatever he had wasn’t helping the upright at all, but then it could be the lesser audio. So, I’d guess a V4b or B25 head. At times it almost looked like a VT22 combo, but the camera was moving around so much, could have been an illusion, and I only made it through half of the video. Maybe a Fender Showman cab? I looked up other videos by them, better shot, and looks like he(if it’s the same guy)moved to Ashdown and Markbass. Why are you interested? From where I sit, it wasn’t anything special.
