I am definitely no expert but I I have a pocket pod (which I love) and the same thing happened to me re loud hum, but I changed the fairly high maximum output mains adaptor for a low 300ma maximum one I got with a zoom pedal, and the hum went away! It shouldn't make any difference what the maximum amp load is, and maybe that wasn't even the problem, but using a different adaptor totally cured it - why I don't know, but maybe it's worth a try..?

Update: I have tested all sockets in my house and all are earthed correctly. Problem must be with earth in the Pocket POD and HD500? Can anyone from Lie 6 advise?

I strongly suspect that it is the circuitry in your house rather than both devices. It may be very localized - have you tried using different electrical outlets throughout your house? Can you test it in another house/location?

You may need a power 'cleaner'. I don't know exactly what they're called but there are products that will eliminate hum.

I own both of these units and am experiencing the same issue with both of them. When using power from a wall socket (using recommended adaptors), I get a noticeable humming noise. When Itouch something metal on my guitar or the units the hum is reduced. Also, when I connect the units to my computer via USB, the hum is greatly reduced.

I have tried several guitars and cables and the problem persists. I think the problem is either with the units or the ground in my house electrical supply. However I cant see how it is the house as the problem goes away when I connect to a computer via usb.....the computer uses the same power source!

Please help !!

Thanks
