The loop has two in it.
L1 - Sub N Up
L2 - Empty - I am leaving this open for other options when I need it
L3 - Super OD
Now, I can do all kinds of monkeyness, like add another OD, DIST, Octaver depending on the situation. I can then have my own little loop however I want it and I always like my own OD in there whether its Blues or just regular OD or Super OD.
This is the chain now
Tuner -> Darkglass Vintage -> MS3 [OD + EMPTY + Sub'n'Up] -> Spectra Comp -> Spark
Now, I can let the DG bypass run a guitar (acoustic/electric) in there and then use the Super OD with the guitar + FX or the Sub'n'Up with bass and the onboard FX block then the Spectra Comp works with both and the boost is mainly for guitar. I also have room to expand whatever I want and I have enough patch cables to make another three pedals fit on the board too if they are minis like my HoF or Corona or Tube Screamer Mini or put them in some kind of internal loop mix as well. Spent this morning jamming with a friend before our practice tomorrow and he said he wants one too because it just opens up so many possibilities.
