3Leaf Audio Wonderlove
3Leaf makes the claim on their website that this is the most versatile envelope filter available. That may or may not be the case, but what is for sure is that this pedal is fantastic. It is incredibly versatile, it has absolutely gorgeous sounds, and could not be more fun to play with. The Wonderlove, like all 3Leaf pedals is also built like a tank which makes it that much more desirable. If you can find this pedal, it would be a crime not to try it out. It is important to note that this pedal is no longer in production by 3Leaf Audio. Instead, they make a smaller envelope filter called the Proton.
External Control:EXP
Cost: $$$
HornFX Review
Interface: 2.5/5
This is a pedal that has so many knobs and switches that it can be daunting. That being said, every setting sounds good, which makes exploring this pedal and its various parameters incredibly fun. There is no wrong direction on this pedal.
Versatility: 4/5
Even without the added benefit of different selectable filters, oscillators, or fancy sound generators, this pedal does an immense amount. There are so many beautiful auto-wah sounds in this box that you could get lost for hours just turning knobs.
Clarity of Effect: 5/5
You can achieve perfection with this pedal. If there is classic auto-wah sound you like, you can find it on this thing. The effect speaks incredibly purely and organically. The Wonderlove simply sounds great.
Complexity: High
Live application: 3.5/5
The lack of presets would definitely help in dealing with the vast array of controls. If you want to change sounds you have to do it on the fly, and that can be a challenge. However, this pedal is so much fun to play with and find new sounds on that on-the-fly manipulation of the parameters can prove to be a fun adventure.
