So here is the pic of my core setup as I'll be running for the foreseeable future.
I want to keep this all on a PT Jr. I had a setup on a PT2, but its just bigger than I want to gig with. The three pedals I absolutely need are the Octaver (pedal with the Penguins on it), OFD and the Orbital. I can get away without the Manta (or other filter), but would rather not. I was playing with a setup where I added the Dimension Reverb (a pedal which I love but have little use for with my band) and a Line6 M5 which was being used as a midi controller and for its great pitch shifting abilities on a PTJR, but there was no way to keep the expression pedal on board. The entire thing is powered off a Voodoolabs Pedalpower 4x4. The 4 400ma outputs are plenty for each SB2 to have its own tap. The 4th one is actually running off the 12v tap to the Octaver which gains a little headroom with the extra 3v. It's really a great match for what I am running.
The bypass looper is really key to making it work for me and keeping it on this size of a board. I often use just a drive sound of some sort for the majority of a song and like to bring in modulation for a bridge or chorus. Instead of setting up two scenes, one with modulation and one without and switch between them, its much easier for me to just bypass the Orbital via the looper and bring it in when needed. With a more advanced midi controller you could emulate this in software, but it would be impossible to keep it on a PT Jr.
If I really wanted to add a nother SB2 pedal (remember, the hub can work with 5 at a time), then I could fit it on there by removing the tuner and getting a smaller Octaver, but at the moment, this is the most economical use of space for me.
Only thing bugging me right now is the midi cable itself. The right angle cable seems like a great idea, but for some reason the midi connector on the controller is upside down, so the cable faces up instead of down. I have to use a straight connector, but it means I have to take out the cable when putting the board in its case. Need to open up the midi controller and figure out if I can turn the connector around.
