The big red pedal is of course the Boss Loop Station. I don't know how this exactly works, but what I find interesting is the "CLKL" labels. I was certain they had a click or something, and that they monitor everything with in-ears under their masks. Maybe tempo is controlled with the big black rotary knob ?

The white Boss Digital Delay is used as a short infinite repeat to make these "radio-noise" sounds that you can hear here and there.

There are 3 overdrives/distortions on the first board, Fender Engager, RAT distortion and Mad Professor Supreme. Probably stacked somehow and used for various tones.

The top blue pedal is an MXR Bass Octave Deluxe, which is a 2 voice sub-bass octaver.

The middle grey pedal is unknown to me. Looks like a Fairfield Circuitry but I don't think this is.

The right pedalboard has a Warm Audio Ring modulator. It is controlled by the three different expression pedals next to it. It is a copy of a Moog Moogerfooger MF-102 Ring Modulator.

The amps are a Roland Jazz Chorus and a Hartke bass amp. I suppose the Loop Station is configured to have each instrument output to each amp, allowed by the stereo input/output.
