The Warwick site also shows he uses the following Warwick bass amps and cabs:

amps:
* WN JH PR 40
* WN JH MP 25

cab:
* WCA JH CC 115

Wonder which amps he currently is using...

They are going to that minimalistic approach with no amps on stage so I couldn't find any 2009 live video where we could find that out. But if I would to bet I'd say the Warwick page is more reliable and recent than the Wiki

I've been searching tons of pictures and articles. I don't know that I believe the Line 6 amp/gear listed on Wikipedia. I think whoever put that info there got it off hear-say from one person on a forum. In pics there is line 6 gear on stage, but I think that could just be the guitar players.... Wish we could get more info on this.

I think the EBS site and Warwick site can be trusted much more, like you said. The EBS site is very recent - it says he started using those EBS pedals in Nov 2009.
