The signal chain (starting MSG 2016-17) was as follows:
Languedoc Guitar –> Dunlop GCB-95 Wah –> Custom Audio Electronics 4X4 switchers (loops 1-8 below) –> Komet Trainwreck 60 amps.
Loop #1: Digitech Whammy 2 / Beigel Tru-Tron 3X

Loop #4: Ibanez TS-808 “more” distortion
Loop #5: Alesis Microverb
Loop #6: Shin Ei Univibe
Loop #7: Boomerang Phrase Sampler ver 1. / Ibanez DM-2000 digital delay

The above is confirmed by the photos below, the first of which is Riviera Maya 2017 and the second is MSG NYE 2016-17:
In the above MSG picture, you can see the signal chain pretty clearly laid out, although the order is confusing. There are three rows of buttons, with the top row having four and the other two rows having three, as follows:
1 WHAMMY/MU — 7 BOOM/DM2000 — MOD (DM2000) — HOLD (DM2000)
4 MORE — 6 UNIVIBE — 5 MICRO
2 KLON — 3 LESS — 8 PUSS
