Tone Timeline
The Edge — Tone Evolution
Edge is the guitarist who made delay a compositional language rather than an effect. From the dotted-eighth intro of Where the Streets Have No Name to the shimmering arpeggios of With or Without You, his entire musical identity lives in the time-based effects chain.
1980–1984: Boy / October / War
Early Edge used a Gibson Explorer into a Vox AC30 with a Memory Man delay — a deliberately primitive rig that made the most of extremely simple chord shapes. Sunday Bloody Sunday and New Year's Day used this rig with the delay taps creating the interlocking rhythmic texture.

↑ Korg SDD-3000 replaced the Memory Man — digital precision allowed exact BPM-synced delay times rather than approximate analog settings.
The Joshua Tree era represents the height of Edge's ambient-delay approach. Brian Eno's production influence encouraged more textural, less rhythmically obvious delay applications. Where the Streets Have No Name used an Electro-Harmonix Electric Mistress flanger through a Korg SDD-3000 delay.

↑ MIDI switching enabled real-time preset changes — from clean delay to heavy distortion to ambient shimmer within a single song.
Achtung Baby saw Edge embracing industrial textures, flangers, and the ADA Flanger. The guitar became an electronic instrument as much as a conventional one. Zoo TV demanded extensive MIDI switching of effects for real-time performance.

2004–present: How to Dismantle / Songs of Innocence
↑ Refinement era — trusted classic tools maintained, Korg SDD-3000 reissue brought back the original digital delay character.
Later Edge simplified the chain while maintaining the delay-centric approach. The Vox AC30 and Fender Stratocaster remained central with the Korg SDD-3000 reissue replacing earlier units. Boss DD-20s handled the dotted-eighth patterns that became his sonic signature.
