The Edge — £2,500 · Premium Rig

• The dotted eighth note delay is everything — set delay time to (60,000 ÷ BPM) × 0.75ms and the guitar practically plays itself
• Less gain than you think — The Edge's amp is relatively clean. The chime and harmonic density come from the AC30 and the delay, not distortion
• Single notes and partial chords sound like full arrangements through the delay — you do not need complex chords. A single string can sound orchestral
• Feedback level (Repeats) at 3-4 — enough for 3-5 echoes before dying away. Too much feedback creates mud; too little sounds dry
• Volume swell into the delay — pick very quietly and let the repeated notes swell up. This creates the "shimmer without attack" characteristic of songs like "Where the Streets Have No Name"
• The AC30 Top Boost channel at 7-8 provides the chime — the class-A power amp compression is essential. Do not substitute a different amp and expect the same result
• Tune to standard E — unlike many classic rock artists, The Edge almost always plays in standard tuning. The complexity comes from the delay, not the tuning
• Use a Strat or single-coil guitar — the chime of the AC30 requires the brightness of single coils. Humbuckers muffle the high-frequency sparkle

• ✗Using the same amp EQ as for a solid-body guitar — semi-hollow guitars have natural warmth that makes amp bass and treble settings behave differently. Start flat and adjust from there.
• ✗Using a high-gain distortion pedal instead of amp gain — British crunch amps have a specific harmonic character when driven from their own gain stage. A pedal changes this character.
• ✗Clean amp at too low a volume — even a clean amp provides warmth and tonal character that the pedal sits in. An amp at minimum volume has no character for the pedal to interact with.
• ✗Too many repeats at high mix — more than 3 repeats makes the delay effect accumulate and overwhelm the dry guitar signal. Keep it to 2-3 repeats at a subtle mix level.
• ✗Over-warming the tone — punk guitar benefits from brightness. Too much warmth (low treble, high bass) makes the tone muddy and slow-sounding.
• ✗Complex pedal rigs — punk is deliberately simple. A rack of effects and a complex setup contradicts the genre's philosophy and requires attention that should go on the performance.

Fender Strat or Gibson Explorer into a Vox AC30, with a TC Electronic 2290 or Korg SDD-3000 delay set to a dotted eighth note. The amp tone itself is relatively clean and chimey — all the "music" comes from the delay interacting with the tempo. A Memory Man adds warmer analog echoes on some tracks.
