I'm pretty satisfied with the tone I made for Shine On You Crazy Diamond but I wonder if there's something special to add to it to make the "4 notes" Syd Theme to be sustained more and more... my preset (please don't ask to share it cause my rig is on the tour bus now) has reverb and delays but is there something more (or a precise delay type for example) I can use to have those 4 notes to resonate more and more?
