There's a recent video from the man himself on YouTube about what basses he's using on the latest PG Tour.

I also have a picture of a recent pedalboard of his (no access to my flickr account as I am at work) however it has on it:
A Radial Labs Bassbone
An EBS Octaver
An Ernie Ball Volume Control
An Analogman BiComprosser
An Electroharmonix Deluxe Memory Man with Hazarai
A Boss Digital Delay
A Boss Distortion (the photo is unclear but it looks like a DS-1)
and a Korg Rackmount Tuner
