Hello! Here’s my article dedicated to how Ed makes those sounds.
It doesn’t cover Lotus Flower specifically, but that track is very straightforward, and I’m not really sure I’d even consider it an example of his “Ethereal Tones.” All he uses is a delay set short most of the track, then distortion and a couple of delays during the final chorus.
As I’ve said before, the important thing with Ed’s sounds is not the gear that he uses, but how he uses the specific types of effects that he does.
