MayFly Introduces the Le Canard Envelope Filter

MayFly Introduces the Le Canard Envelope Filter

This feathery little guy is a joy to play because of its incredibly quick response to your right hand - much faster and more expressive than your typical auto-wah pedal.


​If it looks like a duck, acts like a duck, and QUACKS like a duck, then it must be a duck. That's how we came up with the name for our new envelope filter. This feathery little guy is a joy to play because of its incredibly quick response to your right hand - much faster and more expressive than your typical auto-wah pedal. Trevor explains how this is possible in the launch video, as well as gives a demo on Le Canard’s operation.

​The attack control determines how quickly the filter responds to the envelope, and the decay sets how quickly the filter releases afterward. The range controls which frequency spectrum the filter does its magic on. Add to this relay-based full-bypass switching with failsafe, and you've got one crazy little quacky beast. It is so expressive that you'll want to give up on your rocker-wah forever.

The MayFly Le Canard envelope filter features:

  • Super fast responding envelope follower. Touch it and it jumps!
  • Range control to dial in the character of the filter
  • Attack control to control how fast the filter moves on that first touch
  • Release control to control how slowly the filter slides back to baseline
  • Full bypass using relays with Fail SafeTM (automatically switches to bypass if the pedal loses power)
  • Cast aluminum enclosure with groovy artwork
  • MSRP $149 USD ($199 CAD)​
