As many others have, I'm trying to figure out what is being used to get the tone in this clip. I can't seem to find out who this bass player is.
Looks like he has Markbass gear on stage - two 4x10 cabs, but with a production of that size I assume he's going direct and it could be the backline for the festival. In other clips I've seen he's using a Fender jazz 5-string, and in this its a jazz style bass of some sort. They rarely show anything but a glimpse of him (her?).
To me, what's distinctive about this tone is what I would attempt to characterize as the ripping kind of growl, almost as if its breaking up. The tone seems tight and direct, not woofy or muddy at all to my ear.
Its particularly evident when he lays on the B string, and at one point he slides down from E to C.
This is a longer clip, but the tone can be heard most distinctly at these places:
5:48 - 6:09 (the slide)
1:08 - 1:47
The last song is synth bass only. http://www.youtube.com/watch?v=Bfkd3gQ5tCw
Thanks for your comments.
