I’ve always been mesmerized by how giants like Holdsworth and Zappa would push rack delays to their limits.   I designed the Polymoon’s algorithms as a tribute to those sounds while offering an even wider palette of dynamic echoes

Sets the time for the delay and the synchronized phaser
Alt Function: Early Modulation
Triangle waveform modulation of the early delay taps. Ranges from gentle modulation, to FM, to pitch effects.


Sets the feedback amount
Alt Function: Feedback Filter
Controls filter in the feedback path. Set to noon for no filtering, set towards minimum for a darker filter, set towards maximum for a brighter filter.


Adjusts the balance between Dry and Wet signals
Alt Function: Delay Level
Sets the gain of the Wet signal. Ranges from 0dB to -12dB. For auto-scaling, set to min.


Sets the number of delay taps added to the output
Alt Function: Late Modulation
Triangle waveform modulation of the later delay taps. Ranges from gentle modulation, to FM, to pitch effects.


Sets the dimension amount. Dimension smears and sustains the delay tap reflections
Alt Function: Dynamic Flanger Mode
Set to minimum for Envelope Down, set to noon for Envelope Up, and set to maximum for LFO


Sets the intensity/depth of the Dynamic Flanger. Flanger is off at minimum
Alt Function: Dynamic Flanger Speed
Sets the envelope attack time or LFO speed based on the Dynamic Flanger Mode

Hold to access Alt Functions

Alt Functions are only accessible when this button is held

Press to Select Phaser

Slow: Stereo Barberpole phaser with fixed speed of 0.1 Hz
Sync: Stereo Barberpole phaser with speed linked to a quarter note of the delay time
Slow + Sync: Stereo Barberpole phaser with speed linked to a whole note of the delay time


Sets the time for the delay and the synchronized phaser
Alt Function: Dotted Eighth Note
Changes current tempo from 1/4 notes to dotted 1/8 notes
Hold Tap: to engage Half Speed Delay


Disables processing and passes the input through to the output
Alt Function: Dynamic Flanger Feedback
Adds negative feedback to the Dynamic Flanger

Meris continues to hit it out of the ballpark with their effects pedals. The Polymoon is a welcome addition to a saturated market and provides a unique and fun experience for all of you delay nerds.

Recommended for dreamy delay nerds. In a market filled to the brim with delay and modulation pedals, the Polymoon really shines through with something quite different. It does everything from the simplest of delays through to super modulated and pitch shifting soundscapes with ease. The 1200ms of delay gives you a tonne of sonic real estate to play with.The pedal has controls for time, feedback, mix, multiply, dimension and dynamics, as well as a tap tempo switch alongside the bypass switch. Easy to tweak to the desired sound without jumping through a tonne of hoops. I’ve said it before, but Meris make some of the highest quality pedals on the market that also look stunning. The white coated casing is tasteful and built like a bank vault.
