Electro Harmonix Pico Atomic Cluster

Although it's a good idea and chaos is part of it, there is an auto-wah effect going on that produces a constant mid low sound that lowers the overall tone. Handling is also not its strong point as Dynamics mode could get your ear pierced and tracking is weird even for a synth pedal. Maybe it's not working polyphonic as expected.
I returned it since it was difficult to produce a somehow stable chaotic sound like I had it in my mind. I would like this idea to get better first before buying a similar pedal again.

I never thought I’d get R2D2 out of my amp, but there you go!
It’s an interesting little pedal, with some lovely sounds emanating from it. I need more time to explore the full complexities, but so far very pleased with it.
