The Malekko Heavy Industry Downer is a compact pedal that stacks three kinds of sound-shaping in one box: wavefolding or saturation for distortion, pitch shifting down one octave below your note, and both high-pass and low-pass filters for tone shaping. Malekko labels it a wavefolder, overdrive, octaver and filter pedal, and says that in one sweep you can dial your tone from classic, heavy fuzz to screaming experimental madness1. It sits in the wider family of octave and pitch pedals, but with a distortion-first character that sets it apart from a straight octaver.

The pedal was shown as a prototype at NAMM 2018 and released in March 2018, available to order for $18923. gearnews.com noted that it "packs quite a lot into its pink and grey chassis"4.

What the Downer does

The Downer's core idea is combining distortion with an octave-down shift and filtering. The effect combines wavefolding or saturation with pitch shifting down to one octave below, and two filters shape the result4. Because the circuit is a hybrid, it is neither purely analog nor purely digital1.

The two distortion modes work differently. According to Pedal of the Day, "you get to choose from the Wavefolder or Saturation settings, two distortions each with their own output level range"5. Delicious Audio's Christopher Scapelliti explained the difference: Saturation, the more "subtle" of the first two effects, creates the sound of distortion that's produced when audio tape is pushed to its performance limit, while "Wavefolding takes the effect further, creating distortion with extreme harmonics"2. For players curious about the wider territory, the Downer overlaps with distortion pedals and filter pedals as much as with octavers.

Controls

The pedal keeps things simple: one compact package featuring just 6 knobs2.

PreampDrives the Wavefolding or Saturation from subtle to extreme12
Hi PassSculpts the tone further2
Lo PassSculpts the tone further2

The Preamp knob is the main intensity control, pushing the wavefolding or saturation stage from subtle to extreme1. The Hi Pass and Lo Pass filters then let you sculpt the tone further, which is where the Downer's synth-like character comes from: filtering a wavefolded, octave-down signal is what gives it the range from heavy fuzz to experimental sounds RockBoard's PedalPedia describes1.

Expression pedal and power

One of the Downer's more unusual features is its expression input. You can assign an expression pedal to your own combinations and settings within the pedal's features1, and Delicious Audio described this as "assignable expression pedal control over any combination of the device's knobs and settings"2. In practice, that means one expression pedal sweep can move several parameters at once, which suits the pedal's experimental bent.

The Downer draws 50mA at 9V DC, center negative1. Delicious Audio reports it can also run from an internal battery2, so check your power supply polarity before adding it to a daisy chain.

What reviewers said

Coverage of the Downer was largely descriptive rather than comparative, but the theme across outlets was the pedal's experimental range. MusicRadar's headline framed it as a pedal that will "turn your guitar into a raging fuzz synth"3, and gearnews.com grouped it with Malekko's other 2018 releases as pedals that "invite experimentation"4. Pedal of the Day highlighted the two distinct distortion modes and their separate output level ranges5.

Malekko's own framing is the boldest claim on the page: "in one sweep, you can dial your tone from classic, heavy fuzz to screaming experimental madness!"1

Questions

What does the Malekko Downer do?

The Downer combines three effects in one compact pedal: wavefolding or saturation for distortion, pitch shifting down one octave below your note, and both high-pass and low-pass filters for shaping the tone. Malekko says that in one sweep you can dial your tone from classic, heavy fuzz to screaming experimental madness.

Can you use an expression pedal with the Downer?

Yes. The Downer lets you assign an expression pedal to your own combinations and settings within the pedal's features, so one pedal can sweep any combination of the Downer's knobs and settings as you play.

What power does the Malekko Downer need?

The Downer runs on 9V DC, center negative, and draws 50mA. It can also be powered by a standard 9-volt DC center-negative adapter or an internal battery, according to Delicious Audio's report on the pedal.

Is the Malekko Downer analog or digital?

Malekko's product page on RockBoard's PedalPedia lists the Downer as a hybrid circuit, meaning it combines analog and digital stages rather than being purely one or the other.

Does the Downer have an octave down?

Yes. The Downer pitch shifts your signal down to one octave below, and it combines that with wavefolding or saturation and high-pass and low-pass filters.
