I had a hum problem with a Tascam US-122. I wanted to record a singer and guitar that had an integrated pickup. The singer's mic was a condenser and so needed phantom power so I had phantom power on, but I also had the guitar pickup plugged into the other channel. If I turned phantom power off the hum went away.
I haven't had the problem with balanaced line either and in the end we just went for a second mic on the guitar which avoided the hum.
