  I lived in a house once where a horrible buzz spontaneously took over my 
  guitar amp, on and off, seemingly randomly for months and months. It was 
  horrible. 
  
  I finally noticed it happening a few times when house mates came home and 
  immediately went downstairs and realized that the living room light was on a 
  dimmer switch, the only one in the house. If the dimmer was not at full, the 
  guitar amp was practically unusable for the loud buzz. 
  
  So... check for evil dimmer switches anywhere on the line, especially if 
  it is an older house. 
  
  When I put a studio in my basement, I made sure the power to the audio 
  outlets was wired independently.
