well that thing is obviously some kind of video editor with a load of stuff bolted onto it, i didn't think it was actually one whole instrument with a guitar neck!
If you pause that video at 0:26 you can clearly see that the screens are two of those mini TV's you can get for about £5 off ebay, painted grey and bolted onto the back of the video mixer. You can even see the tuning knobs on the side and the aerials folded onto the back.
