I am not a guitarist and this description is therefore not of direct concern to me, BUT: your research and this video with the details of the patches really deserve congratulations! The modular synthesizer is exactly this alchemical practice, a search for the transmutation of sounds: from the common to the rare (lead/gold).
The modularist's setup is an achimist's laboratory.
Very nice work!
PS: the result (at 9:08) reminded me of the opening scene of Return of the Jedi where C-3PO and R2-D2 enter Jabba the Hutt's Palace :)) The participation of Wogglebug and Afterneath (a great pedal) is of course not unrelated.
