Looks like a fender jazz but im not sure.....

Either a Jazz, or some kinda Jazz copy. I couldn't see any logo on the headstock.

Looks like a black on black Squier with the headstock logo covered or remove. Clearly a candidate for the "best bass for metal".

On a side note, though I don't care much for the band, that video appeared to be extremely low budget, very surprising a huge corporation like Yahoo had something to do with it. The production reminded me of a public access television job.

I was thinking it was a jazz but I don't see too many in all black with a black headstock.

The video was just a live performance but I see your point. That bass is goodlooking tho!
