I'm confused by this comment. I gave a picture of the issues with the terrarium board and only talked about the PedalPCB terrarium board in my comment.
It's like yeah, but I have the Daisy Patch with no such noise. It's possible to design it to work. And it's possible for that design to completely eliminate any noise from the signal.
Yo just to chime in, none of you are going to fix the ground issue. And it's NOT the Daisy's fault. This circuit PCB is TERRIBLY designed. They are mixing a computer chip digital ground plane heavily with the analog ground. No wonder you're all getting noise. Seriously, whoever did this maybe...
