Crybaby wah pedal noise problem

Can anyone tell how to fix this problem

The fix is simple: rotate your power supply 180 degrees. I've learned this the hard way: the power supply has to be parallel to the wah, not perpendicular. If you take your pedalboard and simply rotate it, you will see the noise disappear. The power adapter introduces interference otherwise.

Hello. I just came across your video. I have the same problem now. How have you solved it?

[BanjoSkeleton]

Do you use a vibrato pedal or is your string vibrato that insane?

Does this happen when you use batteries to power your pedals?

Sweetwater says your cables could be an issue as well
