First things first, Wes starts things off into a small 4 channel Behringer mixer. He says the reasoning for this is to balance active and passive basses or for when he wants to run a synth through his board. For the sake of your basses you can level that out with a compressor (which I see you have in your chain) or a boost like the MXR Micro amp. It'll make things easier for you, and free up space on your board too. From the mixer things kick off into the ubiquitous BOSS TU-3 Tuner into a Wampler Ego Compressor.
From the compressor is an Earthquaker Devices Bit Commander into an Aguilar double team of the Filter Twin and the Octamizer. I would put the Octamizer closer to the Bit Commander and then you can either put the Filter Twin in front of it or behind it to taste. Wes mentions that he's got a Mutron III and an MXR Auto Q that he'd occasionally swap out with the Filter Twin. You should absolutely, positively rock the Mutron as often as you can. They are some of the best pedals ever made.
The one thing I will absolutely say, is to clean up your board. Organizing your cables and chain will be a headache at first, but when you start using it regularly it will be absolutely seamless setup and take down. You've got a lot of space to work with too. Trust me, you don't want the hassle of scrambling to figure out what went wrong during a set! Anyways, those are just my two cents.
Thanks, Wes, for sending in your board! You've got a lot of great pedals here with a lot of potential for great sounds. If you haven't sent in your board yet, you can email me at email@example.com and it could end up here, on Pedals And Effects.
All of these pedals, and more, are available at Reverb.com!
