I put together a small board to be more portable and suit the Squier CV Bass VI, with a Harley Benton combo PSU and Tuner to start. It's not the neatest with those power cables sprouting out the back, but it otherwise works great.
MXR Bass Octave Deluxe - don't know if I really need it on this board, considering getting a small compressor for this space. My Orange Kongpressor is twice the size.
Mosky Silver Horse "Klon": I might get a Golden Horse to replace it on this board, since I don't need both modes and it's not a lot of money. Nice for just a bit of dirt / mid boost.
Tone City Matcha Cream, green Russian Big Muff clone. Brings the dirt.
The Boss MD-200 is back for now since my JHS 3 Series Phaser has apparently died on me. It's a bit overkill and I could fit two pedals in that space. I have a mini size chorus/tremolo (Mooer Soul Shiver), the space could fit that and another mini phaser.
Sonicake Sonic Ambience: delay/reverb, pretty good if a bit fiddly.
IK Multimedia ToneX One: I have it on this board as an amp/cab sim with headphone and USB interfaces at home. Won't be needed if playing through an amp, but could be useful in a direct to PA situation. "The Fridge" preset gets used the most but I also have a cleaner Trace Elliot model on there.
