The Edge's Sound

That chiming, echoing guitar is a technique more than a trick: a delay set to a dotted eighth note, timed to the song's tempo. Play with it below.

Set the tempo, tap a note, and listen to the repeats fall between the beats. Inspired by the rack delays Edge made famous, like the Korg SDD-3000 and TC Electronic 2290.

Delay time

357 ms

The math: one beat is 60,000 ÷ BPM milliseconds. A dotted eighth is three-quarters of a beat. At 126 BPM that's about 357 ms, and the echoes land in the gaps, so one guitar sounds like two playing an interlocking part.
