nice clip.

i built my rig to create this type of stuff. there’s an obvious lack of attack when he strums, so this could be reverse reverb almost completely wet, delay twisted up, with a dab of feedback to keep the reverb repeating into the distance. it sounds like you could use your DL4 to create the ambient loop, and octave up your pog2 (slow attack) for that high lead. he’s definitely got some chorus (you could use pog2 detune) in there as well.

hell, if you wanna spice that up, add a trailing delay, perhaps a normal reverb on top of that, and tremolo it up for some shimmers. very lite phasers work in these cases pretty well too, especially something that can be controlled via expression pedal.

think about reverse delay as well. sometimes people try to recreate the “kevin shields effect” and do not consider that a lot of those chords merging together can be accomplished with reverse + trailing delay as well.
