 The Edge's Delay Settings > All I Want Is You (94 bpm)

• Starting at time 0.00 at the beginning of the CD single version, the sample runs from [1:24.75-1:25.25 secs].
• In the sample you hear Edge's pick attack on 2 notes (one low and then one higher) and then the delay of the first note, while Bono is singing. There's 1 short echo (~5ms) on the notes, but nothing like most of the other songs I've looked at. That echo could easily be room echo, so I'd say no 'short delay' on this song.
• Note: Edge's delay is set to 425ms which is not in an obvious time with the song's tempo (94 bpm). This is a very rare case. Edge usually uses a delay time of 3/16 which would have been 484ms in this case, which may have been too long to be coherent so he chose a slightly shorter delay.
• The 425ms is equal to a 1/3 of a 'quarter note triplet'. There are 4 1/4 notes per bar and 2 1/4 note triplets; each triplet has three notes each. So 1/3 of a quarter note triplet is equal to 1/6 of the length of a bar. This sounds a bit out of step with the song's rhythm, but that idea matches the slightly off-key guitar solo in the song.
• On the acoustic guitar, there's a delay of 325 ms (= 1/8 @ 93 bpm) with 3-4 faint repeats. You can hear it here, slowed down 4x.
• On Bono's voice, there's a delay of 125 ms. You can hear it here, also slowed down 4x.

 Here's the sample clip I studied for this song (it's slowed down 4x maintaining the same pitch and matches the waveform in Figure 1)

 There's 1 delay and it's panned right. This is the most likely signal path: ``` Guitar -> Signal split to A/B: A -> amp #1 (panned left) B -> 425ms (1 repeat) -> amp #2 (panned right) ```
