About This Item
Description
The Meris Polymoon stacks a 1200 ms multiple-tap delay with six custom LFOs, a tempo-syncable barberpole phaser, and a dynamic flanger for tidal, dream-state soundscapes.
Which Meris Polymoon is this?
Polymoon is a fixed-architecture 1200 ms super-modulated multi-tap delay with six knobs, two footswitches, and 16 presets. Meris notes that the modular LVX "borrows many processing elements from the Enzo/Hedra/Polymoon," but cannot completely replicate Polymoon's unique engine — LVX runs up to 2540 ms dual delays, a 60-second true-stereo looper, a color screen, and 99 presets across 33 banks, and is sold as its own pedal on our site. Meris suggests pairing the two for even greater possibilities.
Why guitarists choose the Polymoon
- Up to 1200 ms of multi-tap delay creates dense, evolving echo textures beyond a standard single-tap delay.
- Six custom LFOs continuously modulate the delay taps for tidal, ever-shifting movement.
- Tempo-syncable barberpole phaser and dynamic flanger add swirling motion without extra pedals.
- 16 onboard presets store your favorite modulated-delay soundscapes for instant recall.
- Trails-enabled bypass lets delay and modulation tails ring out naturally after you switch off.
- MIDI over the multi-function EXP jack unlocks full remote control with the Meris MIDI I/O.
Controls and switches
- Time / Early Modulation (Alt) — Sets the base delay time up to 1200 ms; Alt sets the depth of modulation applied to the early delay taps.
- Feedback / Feedback Filter (Alt) — Controls how many times delay repeats feed back into themselves; Alt tilts an EQ filter inside the feedback path for brighter or darker repeats.
- Mix / Delay Level (Alt) — Blends delay with dry signal; Alt trims delay output level from 0 dB down to -12 dB.
- Multiply / Late Modulation (Alt) — Sets how many delay taps are added to the output for denser repeats; Alt sets modulation depth applied to later taps.
- Dimension / Dynamic Flanger Mode (Alt) — Smears and sustains reflections for added dimension; Alt selects the Dynamic Flanger's response mode — Envelope Down, Envelope Up, or LFO.
- Dynamics / Dynamic Flanger Speed (Alt) — Shapes overall dynamic response of the modulated repeats; Alt sets the Dynamic Flanger's speed.
- Phaser select button — Chooses Slow (fixed 0.1 Hz), Sync (locked to a quarter note of the delay time), or Slow + Sync (locked to a whole note) for the built-in barberpole phaser.
- Tap footswitch / Dotted Eighth (Alt) — Taps in delay and synced phaser time; hold for half-speed delay. Alt switches the tapped subdivision from quarter notes to dotted eighth notes.
- Bypass footswitch / Dynamic Flanger Feedback (Alt) — Engages or bypasses the effect; Alt sets feedback amount for the Dynamic Flanger.
Power and pedalboard compatibility
Polymoon runs on 9V DC, center-negative, 2.1 mm barrel, drawing about 150 mA — well within range for a standard isolated pedalboard supply. A power supply is not included. The True Bypass relay is mono, so Polymoon sits fine anywhere in a standard mono chain; with Trails enabled its delay and modulation trails ring out naturally after bypass, and most players place it last or near-last in the chain, after drive and modulation. For instant preset recall or full MIDI control without a computer, pair it with the Meris Preset Switch and the Meris MIDI I/O.

FAQ
How long is the delay?
A 1200 ms real-time selectable multiple-tap delay line.
What does Multiply do?
It sets how many delay taps are added to the output for denser, more layered repeats.
How many LFOs does Polymoon have?
Six custom-tuned LFOs with adjustable waveforms, split into separate Early and Late Modulation.
What phaser modes are available?
Slow (fixed 0.1 Hz stereo barberpole), Sync (locked to a quarter note of the delay time), and Slow + Sync (locked to a whole note).
What is the difference between Polymoon and LVX?
Polymoon is a fixed 1200 ms multi-tap delay engine. The LVX is a modular delay system with up to 2540 ms dual delays, a 60-second true-stereo looper, and 99 presets, and cannot fully replicate Polymoon's engine — the two pair well together.
Can I recall presets without MIDI?
Yes. The first four of Polymoon's 16 presets are reachable with the Meris Preset Switch, and all 16 over MIDI with the Meris MIDI I/O.
What power supply does Polymoon need?
9V DC, center-negative, 2.1 mm barrel, drawing about 150 mA. A power supply is not included.
