Yep...the drum machine on the left does look like a BK-7M...probably because it's more than likely a Boss DR-series and they are made by Roland.

He's had that same one in videos dating back quite a while.

And yes, DonM, the whole performance is made extra impressive considering he's playing all parts "live"...even when he is using just right hand and bass pedals, it never really sounds like it's missing anything.

He is so smooth that it looks deceptively easy.
