Bass Crybaby noise / EM Interference with Power Supply

[subexpression]

My Dunlop GCB-100 is picking up severe EMI from being mounted above my VooDoo Lab Pedal Power ISO 5 power supply. Moving the pedal 6" away reduces the hum, and 12" away eliminates it. But, since the pedalboard is small, there's no way to place it far enough away from the PS. I'm thinking it is the inductor picking up EMI from the power supply. What exactly can be done to adequately shield it? Copper tape? Faraday cage?

Rotating the power supply might help. Just a thought.

There's really no way to rotate the power supply. It mounts in only one direction in the Pedaltrain pedalboard.
I suppose I could try flipping it over.

I'm surprised that hardly anyone else is experiencing this and VooDoo Lab doesn't have any information pertaining to EMI when a pedal with an inductor is mounted in its general vicinity.
