Easy Chords Big Sound

Six loops built from the simplest open-string shapes on the guitar — nothing above the third fret, most chords two or three fingers, everything ringing wide open. The secret: easy chords in unexpected orders sound more interesting than hard chords in predictable ones. The Broadcast and the wet/dry split make them enormous.

Late Night Easy

Broadcast at 9 o'clock. These voicings are full of open strings ringing into each other — the Broadcast's germanium warmth makes those open-string interactions bloom rather than clash. BigSky on a hall or shimmer. Let everything ring. The open strings do the arranging.

Loop 1 — The Coffee Shop

Em7 → Cmaj7 → Am7 → D. Four shapes, all two fingers or fewer except the D. Every chord shares open B and high E strings — the top two strings never move, the bass and middle voices shift underneath. Loop it, let everything sustain, and it sounds like a record. The Cmaj7 is the money chord — one finger on the B string, everything else open.

RIFF · The Jangle Arpeggio

Let It Ring

Don't strum — arpeggiate. Pick each string individually, low to high, and let every note sustain into the next. The open strings create a harp effect without any effort. Through the BigSky the sustain tails overlap and the chord becomes a wash. The Broadcast adds warmth to the low strings and shimmer to the high ones because the germanium saturates the louder bass notes more than the quieter treble — natural compression from the circuit, not from a compressor.

   (arpeggiate, let ALL notes ring into each other)

Loop 2 — The Midnight Float

Cadd9 → Em → Dsus2 → Dsus2. Three shapes, maximum two fingers each. The Cadd9 and Dsus2 both have the open B and high E ringing, and the sus2 has no third — it floats between major and minor, which means the mood is yours to set with the lead. Two bars on the Dsus2 gives the loop a long exhale before it goes around.

RIFF · The Swell Loop

Volume-Knob Pads

Roll the guitar volume to zero, fret the chord, pick all six strings, then swell the volume in slowly. The attack vanishes and the chord blooms from silence like a synth pad. The dry Badger catches the swell's arrival; the wet Mesa's BigSky catches the sustain tail. Two different instruments from one volume knob. This is Session 03's swell bowing exercise applied to chords instead of single notes — and it's easier because you're not managing individual notes, just shapes.

Loop 3 — The Wrong Key

Am → Fmaj7 → G → E. Three standard open shapes plus an E major — but the E major is the outsider. In the key of Am, the E chord should be Em. Making it E major introduces a G♯ into a key that wants G♮ — and that tension, that one note of wrongness, is what makes the loop hypnotic. It's the same major/minor rub as the Delta Blend from Session 02 and the trapdoor from Session 01. Different clothes, same skeleton.

RIFF · The G/G♯ Toggle

One-Finger Key Change

Over the Am–Fmaj7–G bars, play phrases using G♮ (open G string). When the E major arrives, add one finger: fret 1 on the G string. That's G♯. The entire harmonic world shifts from natural minor to harmonic minor with one finger moving one fret. The Broadcast makes the G♯ glow because the germanium responds to the increased tension in the harmony — the same physics as the Delta G/G♯ rub but in a minor key.

The Greasy Side · All Open · Broadcast at Noon · Slapback Echo

Saturday Night Easy

Broadcast gain trim at noon — audible grit, cleans up with volume. Low-cut at 1 o'clock. TimeLine on slapback (80–120ms, one repeat). These loops want to groove, not float. Strum hard, mute harder, let the open strings bark through the germanium.

Loop 4 — The Porch

E → A → E → B7. The simplest blues progression that exists. Three shapes, all open, all learned in week one. But here's the thing: run this through the Broadcast at noon with a slapback and it sounds like a record. The simplicity is the point — there's nothing to hide behind, so the groove, the dynamics, and the Broadcast's texture are the whole show.

RIFF · The Broadcast Crunch Test

Dynamics Only

Strum the E chord at five different volumes without touching any knobs. Whisper. Talk. Shout. Scream. Then the volume knob rollback. The Broadcast at noon responds to all five differently — from warm clean to breaking up to full grit to woolly to clean-via-knob. This is the whole point of the pedal: five sounds from one setting. If all five sound the same, the gain is too high.

Loop 5 — The Campfire Shuffle

G → C → D → C. The most played chord progression in the world. Three shapes. Your gran knows them. But shuffle it at 66% swing, mute between strums, and run it through the Broadcast with slapback and it stops being a campfire and starts being a roadhouse. The lesson: the groove is the arrangement, not the chords.

RIFF · The Chuck Scratch

Muted Shuffle Strum

Swung 8ths. The downbeat is the chord, voiced and ringing. The skip note is a fully muted scratch — left hand releases pressure so the strings buzz dead against the frets. Chord-scratch-chord-scratch. The scratches are the groove; the chords are the melody. The Broadcast's germanium makes the scratches percussive rather than silent — you hear the pick hitting dead strings through the transformer saturation, which turns the mutes into a snare ghost note. Through the dry Badger it's a rhythm guitar. Through the wet Mesa's slapback it's a rhythm section.

Loop 6 — The Outlaw Drone

Em → G → D → Am. The open E and B strings ring through every chord change — they're common to all four shapes. The low E drones underneath Em and rings sympathetically under the others. This is the country-rock progression that Waylon Jennings, Neil Young, and Chris Stapleton all built careers on. It never gets old because the drone never lets it fully resolve — it just keeps rolling.

RIFF · The Hill Country Crossover

Session 02 Meets Open Chords

Run Session 02's Burnside drone riff under these chord changes. The riff doesn't change — the chords change above it. Same principle as the Hill Country one-chord drone but the harmony now moves while the riff stays still. The Broadcast makes the riff's low E bloom into the chord changes rather than fighting them. This is where Sessions 02 and 09 meet, and the loop becomes something neither session could produce alone.

The Open-String Rule

Every loop in this session shares at least two open strings between every chord change. That's the design principle. Those shared open strings are the thread that holds the loop together — they ring through the changes and create a harmonic continuity that makes simple chords sound arranged. The Broadcast's germanium warms those shared open strings. The BigSky extends their sustain into the next chord. The wet/dry split lets the attack live in one amp and the sustain live in the other. The architecture is doing the work. The chords are doing nothing except being easy and staying out of the way.

Broadcast Settings for Open Strings

Jazz side: gain at 9 o'clock, low-cut at noon. The open strings ring long and the germanium warmth is subtle — a colour, not a texture. You want to hear the chord, not the pedal.

Greasy side: gain at noon, low-cut at 1 o'clock. The open low E will get muddy if the bass isn't trimmed. The higher low-cut keeps the bass tight while the germanium adds grit to the mids and highs. You want to hear the pedal making the chord better.

Both sides: AC+ always on underneath. The AC+ pushes the Broadcast harder without adding its own character — transparent boost into characterful preamp. The Broadcast responds to the extra input level by saturating more, which is the same physics as turning up an amp. The AC+ is your volume knob for the Broadcast's behaviour.
