Sur l'original de Heroes, je crois que Robert Fripp utilise un ebow pour le son "sustain infini"

Everyone who's played the song with Bowie since then has had to use an E-bow to duplicate it, but Fripp had a technique in those days where he measured the distance between the guitar and the speaker where each note would feed back. For instance, an 'A' would feed back maybe at about four feet from the speaker, whereas a 'G' would feed back maybe three and a half feet from it. He had a strip that they would place on the floor, and when he was playing the note 'F' sharp he would stand on the strip's 'F' sharp point and 'F' sharp would feed back better. He really worked this out to a fine science, and we were playing this at a terrific level in the studio, too. It was very, very loud, and all the while he was playing these notes Eno was turning the dials and creating a new envelope and just playing with the filter bank. We did three takes of that, and although one take would sound very patchy, three takes had all of these filter changes and feedback blending into that very smooth, haunting, overlaying melody which you hear.
