I just got a power supply for my pocket pod express. It's not a line6 supply but it is to the right spec. When I use this I get a slight background hum/crackle which I don't get with the Battery.

If I move the wires around and handle them the noise changes and it's worse in some poritions than others. It seems like there is perhaps some interference on the input signal as the guitar input jack and the power input are right next to each other.

Have you any idea how I can fix this ?
