Well for sure it’s the crystals effect. Definately not all pure h9’d (he does step on something at the end while the h9 is at the back).
If i were to guess: An od/not so agro fuzz set to mid-high if od gain/low vol/tone rolled > a looper just to make that initial 2 note freeze type bed > h9 set to crystals pitched 1up. Then 2nd part he engages a whammy. Tadah
