EHX Micro POG Settings Guide

The EHX Micro POG (Polyphonic Octave Generator) adds sub-octave and/or one-octave-up voices to the guitar signal. Polyphonic tracking means it works on chords, not just single notes — making it more versatile than older monophonic octave pedals like the Boss OC-2. Three controls independently adjust Dry, Sub Octave (one octave down), and Octave Up (one octave up) levels, allowing any combination of voices.

Used by: Jack White, Justin Vernon (Bon Iver)

The best EHX Micro POG settings start with: Dry at 8/10, Sub Octave at 0/10, Octave Up at 0/10. Adjust from there based on your amp, guitar, and room volume. For Organ Simulation: Dry 7/10, Sub Octave 6/10, Octave Up 0/10.

Settings by Genre

Organ Simulation
Dry7
Sub Octave6
Octave Up0

Dry blended with Sub Octave — the two-voice combination (dry + one octave down) resembles the left hand/right hand voicing of a Hammond organ. Running this into a slightly overdriven amp adds the harmonic richness that completes the organ simulation. Works best on single notes and fifth intervals rather than full chords.

12-String Simulation
Dry8
Sub Octave0
Octave Up7

Dry blended with Octave Up — one octave up voice combined with the fundamental produces a 12-string-like shimmer. The Octave Up voice is clean and precise, and at moderate levels blends convincingly with the fundamental to produce additional harmonic sparkle without obvious pitch-shifting artifacts.

Bass Simulation
Dry3
Sub Octave9
Octave Up0

Dominant Sub Octave with reduced Dry — the guitar plays in normal register but the sub-octave voice dominates, producing a bass-guitar-like tone. Works well for solo guitar performance where bass lines need to be present without a bassist. Works best on single notes above the 5th fret.

Full Harmonics
Dry7
Sub Octave4
Octave Up5

All three voices active — dry fundamental, sub octave below, and octave above simultaneously. A rich, harmonically full sound that sustains naturally and works for ambient, psychedelic, and experimental playing. Into heavy reverb and delay this produces a piano/organ hybrid texture.

Artist Settings

Documented settings used by professional guitarists on this unit.

Dry6
Sub Octave8
Octave Up0

White uses octave pedals (Micro POG and others) to generate bass-like sub-octave tones that fill the low register of his stripped-down two-person band format. The sub-octave voice allows guitar riffs to simultaneously address both guitar and bass frequency ranges, which is essential in a guitar-drums duo.

Dry7
Sub Octave0
Octave Up6

Vernon uses the Micro POG in his ambient, atmospheric production for the shimmer and harmonic extension the Octave Up voice adds to guitar textures. At moderate Octave Up levels with heavy reverb, the effect contributes to the ethereal, layered quality in Bon Iver's studio recordings.

Tips & Common Mistakes

  • The Micro POG is polyphonic — it tracks chords accurately. This distinguishes it from the Boss OC-2, which is monophonic and only works reliably on single notes. For chord-based octave applications, the Micro POG is the correct choice.
  • Signal chain position significantly affects the Micro POG's behavior: placed before overdrive, the octave voices are distorted along with the fundamental. Placed after overdrive, the distorted fundamental goes into the POG and the octave voices are added clean. Both work but sound different.
  • The tracking speed of the Micro POG is very fast compared to older analog octave pedals — it produces notes nearly instantaneously without the pitch-lag artifact of the OC-2. This makes it more usable at higher tempos and with busy, melodic playing styles.

EHX Micro POG — Common Questions

Best starting settings for EHX Micro POG: Dry at 8/10, Sub Octave at 0/10, Octave Up at 0/10. Adjust from there based on your guitar, room, and playing style.

For Organ Simulation: Dry 7/10, Sub Octave 6/10, Octave Up 0/10.

For 12-String Simulation: Dry 8/10, Sub Octave 0/10, Octave Up 7/10. Dry blended with Octave Up — one octave up voice combined with the fundamental produces a 12-string-like shimmer. The Octave Up voice is clean and precise, and at moderate levels blends convincingly with the fundamental to produce additional harmonic sparkle without obvious pitch-shifting artifacts.
