I just ran a test using a built in drum machine on my old Farfisa so I could have a steady source signal. So, I still get the buzz, however the signal comes through the amp and the DI box, which is good. My guess is maybe since the amp head is plugged into a different circuit (different room, different plug) from the mixer it's causing the buzz. I had a similiar problem before where my computer and mixer were in different plugs and it caused buzz.
