Also, your "Ground" source may not be realy Earth Ground.

If you're using the ground screw on an outlet, that may take a high resistance path to real ground and cause a "ground-loop" through your electrical system and cause hum. Depends on your house electrical system. Try a ground clamp to a COLD water pipe, clean, no-paint.
