"That’s going into an Adventure Audio Siamese Growler which is essentially a tube screamer clone with an added boost button for a little extra thickness"

The pedal can be seen in a close up of the pedalboard in this video. https://youtu.be/w31pcaf2d6w?t=1547

"Right now I just have a standard boss tuner going into this neat 70’s DOD Preamp pedal that acts as an always on clean boost when it’s turned up to 10."

This pedal can be seen here when JANK performed live. https://youtu.be/w31pcaf2d6w?t=1547.

Here is a close up of Matt's pedalboard. The DOD FETpreamp is located on the bottom right of the board. https://prnt.sc/xvvtop

"That’s going into an old Japanese Frontline Stereo Chorus...".

It's stated that it is a stereo chorus, but it's infact a mono. The closeup in the video link shows so. https://youtu.be/w31pcaf2d6w?t=1549

"...which has been going into my roommate’s hall of fame reverb, but I’ll be using a Boss RV5 for our upcoming tour in August."

It can be seen in the far left side of the pedalboard when the video comes into focus. https://youtu.be/w31pcaf2d6w?t=1549

they talk about it at 7:22 in the video. lou describes it as a transparent overdrive that can blend the overdrive signal into the clean.

From this screen shot of the pedalboard, you can see the tuner in the bottom right hand corner.
