I wanted to site my Nord G2 on top of my Pianet for my stage setup, and 
the noise was horrible.  The Pianet is full of pickups.  I shielded the 
inside of the Pianet with Mumetal on the underside of the top and the 
sides, bottom has a big metal plate so I couldn't add anything there.

It's not cheap and there's still a little hum but it worked well enough 
to be usable.
