edit:
“Sound on Sound” effect/long delay pad
On the intro on Shine On David is simulating keyboard pad his guitar using a very long delay. The guitar signal travels through a volume pedal (a second pedal used only for the SOS effect) and then into Roland digital delay unit with long repeats at 1500ms (20sec sustained repeats). David strums a chord, lowers the volume pedal and plays a solo fed through the “normal” signal path, while the Sound on Sound pad (the strummed chord) is sustained by the long delay. The pattern is repeated for each chord.
only took five years for me to get the answer
