Whenever I turn my BYOC Chorus on, I get a loud pop. I took a video as a demo but couldn't upload it. It doesn't really matter because the video doesn't really do it justice, but it's an annoying popping sound that comes through when I'm playing. I have ruled out a grounding issue because I'm still getting the same popping sound when it's the only pedal in the chain and it's connected to a solitary adapter. I also notice a low volume sweeping sound coming from the pedal when it's one but I'm not playing. That sweeping sound doesn't change it's rate when I turn the depth or rate knob, it stays consistent.

Any help would be greatly appreciated.
