Here's the latest additions:
RJM Mastermind
Axess GRX4 (looking for a Mini Effect Gizmo!!)
EHX Little Big Muff
Korg Pitch Black

GRX4 Loops:
1. Zvex pedals
2. OLC Chunky Cheese
3. Tweakfuzz (need to make 2 patch cables)
4. Big Muff

So the Mastermind is doing 2 things.
1. Calling up presets on the Timeline & M9
2. Sending CC's to GRX4 for Fuzz box selection. The Mastermind is pretty cool in that you can go into Instant Access mode by hitting the FUNCTION switch. The IA buttons can be set to be mutually exclusive. If you turn one pedal on, it turns off the currently active pedal in the group. Pretty cool. An RJM Mini Effect Gizmo might be in my future so I can have 5 loops in the same size box.

Looks like a cool sounding setup, Jason. Not sure about those patch cables though!
A Mini Effect Gizmo is definitely the way forward - takes up less real estate than the GRX4 and you get an extra loop in the bargain. At the moment you're running the Fuzz Factory and the Mastotron in the same loop?

Yeah, running both Zvex pedals in the same loop knowing that I won't use them both at the same time and they are true-bypass. The RJM MEG would obviously allow me to put them in separate loops.
