I was just recently watching " David Gilmour Live in Concert" a new DVD of him playing stripped down versions of his songs. In the very beginning he is playing some lead acoustic using some sort of expression pedal. when he rakes a chord and presses the pedal a synthetic note/chord? rings out infinitely sounding similar to a keyboard or a choir singing the note. Then he plays some lead licks in between and rakes the next chord, once again pressing the pedal which rings out until he switches it. WHAT KIND OF PEDAL IS THIS? it needs to go on my "must have" list
It's not a pedal but a rack effect. The signal is split in two. One signal goes straight out and the other which he hits a A B switch for.
A Roland SDE-300 provided a long delay that ran to a volume pedal. The signal was then sent into a Fender Stereo Passport PA amplifier. This allowed Gilmour to play the opening of the song over the sustained chords that had been sent to the delay system.
