Mu Metal against humming Wah Pedal

What happens by putting mumetal foil in between of a humming wah pedal and the power supply?

These are 3x 0.5mm Mu Metal foils. Voodoo Pedal Power II and a Morley Bad Horsie.

THIS DOES NOT WORK FOR GROUND HUM PROBLEMS!

But why the hum with the activated Morley Bad Horsie? Although the Pedal Power 2 uses a toroidal transformer design that reduces the magnetic field around it, it seems that the inductor of the wah pedal is still sensitive enough to be affected by the electromagnetic field when being near of the power supply.

Impressive. Did you manage to install this permanently, if so, how?

And was it still as effective at reducing EMI? I've read that its properties can be damaged quite easily by shaping, so I'm curious if you've tried it out!

Thanks man... I installed the mu-metal foils just by putting them under the velcro. So i can't tell you what happens when shaping or cutting them...

Hey i have a question, i just bought a pedal power and i have the bad horsie wah, the wah runs off of a 9v battery, but it says it requires a 300mA adapter, which output should i use on my pedal power? All i have left is the 9v/12v output and the 18v. And if you know, if i have another 9v, 100mA pedal, can i power it in the 18v output?

Thanks, I had the same problem.
