Into stereo (6)

30. KEEP THE WIDTH DOWNSTREAM

Mono modulation → Stereo delay and reverb — The stereo ambient rig, The wet/dry/wet three-amp rig

Wide stereo ambient guitar that stays completely intact when collapsed to mono, six minutes, 80 BPM, spacious and reliable. All the modulation happens before the signal splits: a slow chorus and a gentle phase sweep in mono, woven into the guitar tone itself rather than spread across the stereo field. Only after that does the signal split into two independent paths — a long delay with its repeats spread hard left and hard right, and a large algorithmic reverb running genuinely different processing on each side. The width therefore comes entirely from the ambience, and because delay and reverb sum harmlessly, nothing disappears or thins when both channels are added together. The guitar underneath is clean with a lot of sustain, played with volume swells so notes bloom in from silence rather than being struck. Chords ring into each other over a static harmonic centre that never resolves. The stereo image is very wide but the fundamental tone sits solidly in the middle. Bass is sustained and low; drums are sparse with long gaps. It ends by letting the delay repeats decay across the stereo field for fifteen seconds after the last note.

31. THE COLLAPSE

Stereo rig → Mono PA — The wet/dry/wet three-amp rig, The stereo ambient rig

Guitar music that is designed to work in mono and gains width as a bonus, five minutes, 104 BPM, solid and centred. Every essential element — the drive tone, the rhythmic part, the note attack — is mono, dry and centred, so the piece loses nothing when both channels are added together. The stereo content is entirely ambience: a long delay whose repeats spread outward, and a reverb that decays wider than it starts. Modulation appears only in mono, applied before the split. The result heard in stereo is spacious and enveloping; the same piece heard in mono is slightly smaller and just as intelligible, with no cancellation, no thinning and no effect disappearing. The guitar tone is mid-gain with a strong midrange presence and a hard pick attack. Playing is rhythmic and riff-based, deliberately dependent on timing rather than on texture. Bass and drums are loud, tight and centred. The arrangement builds by adding instruments rather than by widening the image. It ends on a mono unison stop with the stereo reverb tail continuing alone for several seconds afterwards.

32. THE CENTRE HOLDS THE ATTACK

One guitar → Wet/dry/wet — The wet/dry/wet three-amp rig, The rack rig and buffered loop switching

Enormous three-dimensional guitar with a rock-solid centre and vast width around it, six minutes, 92 BPM, cinematic and precise. The dry signal — drive, dynamics, note attack, all of the midrange definition — goes to a single centre amplifier with no time-based effects on it whatsoever, so the pick attack and the fundamental are phase-coherent and locked in the middle of the image. Two further amplifiers, panned hard left and hard right, carry only fully wet ambience: long delays and large reverbs at one hundred percent wet with no dry signal at all, so nothing comb-filters against the dry within any one speaker. The result is a guitar that is simultaneously enormous and completely intelligible, with an attack you could set a clock by and a wash that extends far beyond it. Playing is melodic lead over a slow chord cycle, with sustained notes and wide vibrato. The dry tone is mid-gain and vocal. Bass and drums are large and unhurried. Collapsed to mono the dry centre still carries the entire part. It ends with the centre amp cutting first and the two outer amps decaying for ten seconds.

33. CHECK THE INPUT, NOT THE MARKETING

Pedalboard → Two pedal power amps — The stereo ambient rig, The silent rig

Genuinely wide stereo guitar from a small, portable rig, five minutes, 96 BPM, clean and modern. Two independent amplifier channels are fed from a stereo pedalboard, each driving its own small cabinet placed several feet apart, and the two sides carry genuinely different processing rather than the same signal bounced between them. The drive and compression stay mono and centred because they are inherently mono processes; the width comes from a true-stereo reverb running independent decorrelated processing per side, and a delay whose repeats alternate across the field. The guitar tone is clean with just a touch of grit, bright and articulate, played with fingerstyle arpeggios that let consecutive scale notes fall on different strings and overlap into each other. Both amplifiers are small and identical, so there is no tonal imbalance between the sides — the only difference is the ambience. The overall image is very wide and stable, and the centre is solid. Bass is simple and low; drums are quiet and brushed. There is a mono-summed section in the middle where the width collapses deliberately and then opens back up. It ends on a wide sustained chord.

34. NO CONSENSUS, AND THAT IS THE POINT

Two different amps → Stereo pair — The wet/dry/wet three-amp rig, The two-amp grunge rig

Wide stereo guitar where the two sides are audibly different instruments, five minutes, 108 BPM, unstable and alive. One side is a high-headroom clean amplifier that never breaks up, bright and precise and completely composed at any level. The other is a small, cantankerous valve amp that is already compressing at moderate volume and falls apart into ragged breakup when pushed. The same guitar signal feeds both. The consequence is that the stereo image moves with playing intensity: quiet passages sit centred and clean, and as the playing gets harder the dirty side blooms and compresses while the clean side stays flat, so the whole picture leans and swells to one side. That movement is the effect, and no pedal produces it. Playing is dynamic throughout, deliberately alternating between light and heavy attack to exercise the difference. Both amps are miked in their own rooms, so their ambiences differ as well. Bass and drums are recorded live and centred. There is no modulation anywhere — all width is from the two amplifiers. It ends with a very hard strummed chord that pushes the dirty side into feedback while the clean side simply rings.

35. THE ROOM PROBLEM DISAPPEARS

Stereo rig → In-ear monitors — The profiler and modeller rig, The stereo ambient rig

Intimate, extremely wide stereo guitar mixed for headphones rather than for a room, five minutes, 88 BPM, close and enveloping. The dry guitar sits centred and very close, with the pick attack detailed and immediate, while the ambience extends far out to both sides — a true-stereo reverb with independent processing per channel and a delay whose repeats move across the field. Because there is no room between the source and the listener, the wet levels are noticeably restrained compared to what would be used through amplifiers: the width is achieved by decorrelation rather than by volume. Modulation is gentle and mostly mono, applied before the split, so nothing feels unstable or fatiguing. The guitar tone is clean and warm with a touch of compression, played fingerstyle with sustained overlapping voicings. Every small mechanical noise — fingers on wound strings, the release of a chord — is audible, because the recording is close and dry underneath the ambience. Bass is deep and centred; drums are quiet and intimate. It ends on a chord whose reverb tail spreads outward and decays symmetrically to both sides.
