I think my Pro-10 Green and Noblemen are both possessed

[BeeSharp]

So, I've built a couple of the Aion Andromeda's before and one of those also had this possessed sound. I just finished a Nobleman and a Pro-10 Green - and they both have this possessed power supply sound. However, whenever I kick on another pedal (Tweedman in this case), the noise stops.

You weren't chanting or anything while you were incarnating...er...I mean soldering right?

What power supply?

What power supply?

Its a Strymon Zuma powering the Ojai extension to the pedals

For reference, I had a simple boost pedal that was making a similar sound. In my case swapping IC's and transistors didn't help. The sound stayed the same when I unplugged guitar. I also cleaned up and checked the internal wiring and grounding, no change.

I "solved" it by powering it with a separate power supply from the other pedals. I'd be surprised if your nice Strymon power supply would cause it, but may help you troubleshoot. When time permits, I was going to swap out the power filtering caps on the boost pedal to see if that helps.

It's my Ojai. The main strymon Zuma is not possessed! It also does this with my aion odr and a phase 90 clone too. Strymon is aware, but silent about the issue.
