Kind of interesting to see a bass player's band with . . . another bass player. I wonder what kind of tuning/strings he's using on that. It sounds far too high to be any "normal" string gauge/tuning.
Update: After a little research I found that his Spector is strung with piccolo bass strings (.018-.050). Typically those are tuned an octave higher--making it basically the bottom four strings on a guitar. By way of comparison, I've got .045-.105 on my bass, a fairly typical gauge. Basically, he needs a bass player because he can't truly play the bass parts on that guitar. I wonder what the tension would be like with all of that extra scale length.
