ScottG Practice Lab · Session 09b · Open String Edition Vol II

Six More Easy Ones

Same rules as Vol I — nothing hard, everything open, shared strings between every change. Different moods this time: darker, wider, weirder, and one that's just three chords and a bad attitude.

The Dark Side · Broadcast Low · BigSky on Cloud or Shimmer

Three Loops for 3am

Broadcast at 9 o'clock, low-cut at noon. These loops are darker and more cinematic than Vol I. BigSky on cloud or shimmer — let the wet side do most of the atmosphere. The dry Badger is the anchor; the wet Mesa is the dream.

Loop 7 — The Descent

C → G/B → Am → Fmaj7. The descending bass line — C B A F — walking down step by step while the top voice (open E) stays constant. The G/B is just a G chord with the B bass note — one finger moves, the whole mood drops. This progression has been in every film score, every singer-songwriter's catalogue, and every busker's setlist since 1965 because the falling bass against the static treble creates a melancholy that the brain can't resist. The Broadcast makes the bass walk glow.

RIFF · The Walking Bass

Thumb Does the Descending Line

Pick the bass note with the thumb on every beat — C, B, A, F — while the fingers hold the chord shape above. The bass walks; the treble sustains. Same independence as the monotonic thumb from Session 02 but easier because each bass note only plays once per bar. The Broadcast's germanium saturates the bass notes more than the treble — natural voice separation from the circuit's compression curve.

TARGET · bass line smooth and even, treble sustaining through all four · the bass tells the story

Loop 8 — The Suspended Orbit

Asus2 → Asus4 → Asus2 → D. The A chord with the third removed and replaced by either the 2nd (B) or the 4th (D). The chord never commits to major or minor — it orbits around A without landing. One finger moves between fret 2 and fret 3 on the B string and the entire harmonic centre shifts. The D chord at the end provides the only resolution in the loop, and even that has the open high E ringing (the 9th of D) so it doesn't fully close. Through the BigSky on shimmer this is ambient music from three fingers.

RIFF · The One-Finger Orbit

B String Pendulum

Let the A chord ring. Move one finger between fret 2 (B note, sus2) and fret 3 (D note, sus4) on the B string. That's it. One finger, one string, one fret of movement. The chord breathes in (sus2) and out (sus4) like a pulse. Through the Broadcast the note change is a subtle harmonic shift — not a chord change, a mood change. Through the BigSky the sustain tails of both notes overlap and the chord becomes a living thing.

TARGET · 5 minutes of orbit, no other chords, just the pendulum · what happens at minute 3?

Loop 9 — The Modal Drift

Em → D → C → D. The progression doesn't belong to any single key — it drifts between E minor, G major, and C Lydian depending on which chord your ear calls home. That ambiguity is the sound of The Edge, Radiohead, Sigur Rós. Three shapes, all first-week chords, but the order makes them strange. The open low E drones through all four bars whether you want it to or not — let it.

RIFF · The Drone Underneath

Low E Never Stops

Hit the open low E on beat 1 of every bar regardless of the chord. Let it ring underneath. Over Em it's the root. Over D it's the 9th underneath. Over C it's the major 3rd underneath. Same note, three different harmonic functions, zero effort. The Broadcast's transformer makes the low E bloom and the chords above it float — the bass is warm and the treble is clear because the germanium compresses the low end harder than the highs.

The Loud Side · Broadcast at Noon-to-2 · TimeLine Slapback or Off

Three Loops for Turning Up

Broadcast gain trim from noon to 2 o'clock. These loops want the Broadcast pushed — the germanium breaking up, the transformer saturating, the low strings getting woolly. Low-cut at 1 o'clock minimum to keep the mud out. The dry Badger carries the crunch; the wet Mesa can be slapback, short room, or just off entirely. Some sounds don't need atmosphere. They need volume.

Loop 10 — The Stones Loop

A → D → A → E. Three chords. Keef territory. The open A string is the root of the universe and everything else orbits around it. This loop has powered more songs than any other progression in rock and roll and it still works because the groove is the song, not the chords. Strum it open, strum it muted, hit it with the Broadcast at noon, and it's Saturday night in a room that's too loud.

RIFF · The Keef Hammer

Open-String Hammers

Don't just strum. Hammer into each chord from the open strings: open to fretted, one string at a time, bottom to top. The chord builds itself from the open strings up. The Broadcast makes each hammer-on pop — the germanium clips the transient of the hammer harder than the sustain, so every note has a percussive front edge. Through the dry Badger this sounds like a rhythm section. Through the slapback it doubles.

   bottom to top, fast, let ring — the chord assembles itself
TARGET · all three hammers land within one beat · the chord arrives as one sound, not three events

Loop 11 — The Townes

D → Cadd9 → G → G. Open D country. Two bars of G at the end give it a long porch-sitting exhale. The open D string drones under the D chord and rings sympathetically under everything else. Townes Van Zandt, Gillian Welch, Tyler Childers — this progression belongs to people who play one guitar in a room and don't need anything else. The Broadcast's console warmth is what makes this sound like a record rather than a bedroom.

RIFF · The Fingerpick Pattern

Travis Picking — Thumb and Two

Thumb alternates between the two lowest available strings. Index and middle fingers pick the top two strings in a steady pattern. Same skill as Session 02's monotonic thumb but gentler — the country version. The Broadcast at low-to-mid gain makes the thumb warm and the fingers bright because the germanium saturates the bass harder. Natural EQ from the circuit, not from a knob.

TARGET · full loop Travis-picked, thumb never drops · the wet side should sound like a second guitar

Loop 12 — The Bad Attitude

E5 → G5 → A5 → A5. Power chords. Two fingers each. Open E string on every downbeat. This is the Broadcast on high gain mode — right footswitch, blue LED, the woolly spitting broken-console territory. No BigSky, no TimeLine, no effects at all on the wet side — or turn the wet amp off entirely and run the Badger dry. Some sounds don't want atmosphere. They want a wall.

RIFF · The High Gain Test

Broadcast Modes A/B

Play the loop twice. First pass: low gain mode. Second pass: stomp the right footswitch and go to high gain on the repeat. Same chords, same dynamics, different Broadcast voice. Record both passes and compare. The low gain should sound like a cranked amp; the high gain should sound like a cranked amp that's forgotten its manners. If the two modes sound the same, the gain trim is set wrong — the trim should be different for each mode.

The Complete Open-String Loop Library

Twelve loops across Volumes I and II. Every one of them uses chords learned in the first month of playing guitar. The complexity is in the order, the rhythm, the dynamics, and the rig — not the shapes. A two-finger Em7 through a Broadcast into a wet/dry split with a BigSky on shimmer is a more interesting sound than a seven-note jazz voicing through a clean amp. The shapes are free. The sound is in the signal path.

The Broadcast Across All Twelve

Loops 1–3 (Jazz, Vol I): 9 o'clock. Warmth, not grit.

Loops 4–6 (Greasy, Vol I): Noon. Grit, cleans up with volume knob.

Loops 7–9 (Dark, Vol II): 9 o'clock. Same as jazz but with darker chords — the Broadcast setting doesn't change, the mood does.

Loops 10–11 (Country/Rock, Vol II): Noon. Same as greasy Vol I.

Loop 12 (Bad Attitude): High gain mode. The only loop that uses the right footswitch. The Broadcast earns its rent here.
