Malekko Heavy Industry Polyamorator
The Malekko Heavy Industry Polyamorator is a compact digital harmonize/delay/arpeggio pedal featuring three stages of harmonizing and delay with two pages for control adjustment.
Five of the six knobs change function depending on the page:
- Page 1 has controls for delay time, delay regen amount, stage one harmonizing, stage two harmonizing, stage three harmonizing.
- Page 2 has controls for sample size, wet/dry mix, stage one volume, stage two-volume, stage three-volume.
- The effect is three stages sequentially (arpeggio).
The TIME adjustment changes the delay time for each stage exponentially.
Each stage of harmonizing offers up to one octave up or down, in chromatic increments.
TAP tempo input also works with an external clock. Any combination of Size, Time, Regen, Wet/Dry Mix, Stage One Volume, Stage Two Volume, Stage Three Volume, Stage One Harmonizing, Stage Two Harmonizing, and Stage Three Harmonizing settings, both positive and negative sweep can be controlled with an expression pedal or through CV input.
Polyamorator Features include:
- Delay Time:
- Stage One- 670ms max
- Stage Two- 1.340ms max
- Stage Three- 2.000ms max
- Harmonizing: Range is one octave up or down in chromatic increments
- Size: This determines the amount of audio captured for harmonizing and delaying
- Delay Regen: one repeat to full feedback
- Mix: Set the mix from 100% dry to 100% wet.
- Volume per stage
- Preamp Level – Attenuate or amplify input signal. Unity is at approx. 10 o’clock.
Polyamorator is a signature pedal for Peter Holmström (The Dandy Warhols, Pete
International Airport, Rebel Drones and Radis Noir)

I rely on pedals to bridge the gap in ability by chaining them together to make the weird sounds and then multitracking.
The Polyamorator is a fantastic pedal in that it can produce a light delay with a hint of pitch modulation for a kind of chorus effect, to a heavily delayed arpeggiated and pitch modulated sound that verges on a synth when the regen is cranked up, and everything in between.  What’s more, it even runs well with additional delay (MXR Carbon Copy) and phaser (EHX Small Stone) to further add weirdness without things getting muddy.
It’s a really good pedal and does just what I wanted it to.
