Does anyone have experience adding a ground plane to those white plastic breadboards seen here?

I love using these things as they are easy to get a circuit going. However, I built a mic preamp on one and there is a very low level 60 Hz hum which I'd like to get rid of. I was thinking of taking a piece of copper foil and attaching it to the bottom of the breadboard and making a connection to ground. Anyone ever done this and can say that it does/does not work?
Here is where you can get copper foil cut to size. The price of the copper is reasonable; it's the shipping that kills you.

This preamp is powered by batteries, BTW, so it's not power supply hum.
Many thanks.
