@sunbeamer @Whatwetalkabout I went back forth a lot with my dealer and Make Noise Support - we A/B’d the Mimeo in a few different racks, to rule out power supply/interference issues; I also tested a few different Mimeophon units, and although they all had noise, I do think it’s possible some had more noise than others.
I have heard rumors that Make Noise is working on a firmware fix to address the issue, but if it’s a circuit-layout/bleed issue, then I don’t think it’ll be fixable without a hardware revision.
If I wanted to work around the problem, I would run the Mimeo fully wet, and put a send/return mixer like XOH in front of it - with that kind of signal flow you would have almost no problems; but in the end, I did end up returning the module - I absolutely love the design and sound of the effect, but I am just too OCD about noise.
