  • I recognize the typical 60 cycle hum, and it sounds a lot like that.
  • The hum disappears 95% when I unplug the power source and run on battery. Then the further I remove the power cable from the computer the more the hum disappears.
  • It hums regardless of which pickup is being used, but the tone of the hum changes.
  • The hum is reduced, almost eliminated when I turn the guitar's tone knob to 0.
  • The hum is slightly reduced when I touch the strings or other metal parts.
  • The hum gets louder when i remove the cable from the guitar. Then it disappears if I remove the cable from the audio interface.
  • The hum disappears when I turn the guitar's volume knob off.
