Walrus Audio calls the M1 a High-fidelity Modulation Machine. After running it through its paces, I think it's more than just a multi modulation pedal.

The M1 is a sound design tool made for hands-on studio production. While all the modulation algorithms in this pedal sound great, the real strength lies in its tweakability together with the lo-fi options.

This pedal is made for adding character and vibe to your track. Add some crackle, warble and tasteful lo-fi filtering to your sound and put the cherry on top by picking a lush stereo modulation.

Walrus packed a ton of features into the M1 with all the secondary functions. You can see and hear that there was a lot of research and design going into the making of this pedal.

I've tried to pack a lot of sounds into the demo and show you the most interesting knobs. Go have a look at Walrus' website to read the manual for more info.

Personally, I'm a simple dude. I would love to see a spin-off of the M1 that only has the lo-fi options together with the vinyl and tape vibrato.

In the generation of lo-fi chill & study beats, the M1 is a must-have to just really color your signal in lush to psychedelic modulation and add that lo-fi vibe.

Recording Notes

I tried to keep this one short and simple, because the pedal is complex enough.



  • GarageBand drummer (Liverpool kit, indie rock drummer Gavin)
  • Processed with the M1 to add some grit and lofi character
  • Clean and processed drums panned slightly left and right to create more space in the mix


  • K'mo Memphis (tele pickups, middle position)
  • Keeley Compressor Mini, just enough to make the guitar a little squishy
  • M1
  • Iridium with the usual chime setting

Everything was mixed in GarageBand with minimal post processing.

Signal Chain

  • K'mo Memphis Std., classic T-style pickups (both pickups)
  • M1
  • Strymon Iridium (Chime)
  • Focusrite Scarlett 2i2
