Input Jacks – How to Keep Them Clean

 One very simple maintenence procedure can help keep your guitars’ signal at its best and prevent the loss of ground connection. Clean your jacks! We are talking about the 1/4″ jacks on your amplifier as well as your guitar. Jacks can become oxidized over time and cause grounding problems and resistance in the signal path. ¼” Output jacks can be cleaned by rolling a small piece of #600 grit sandpaper about the size of a cigarette, “plugging” it into the jack and twisted around several times. On old vintage guitars heavy oxidation sometimes builds up and the guitar may not get a very good connection. There have been a few cases where vintage guitars with output jacks so badly oxidized the guitar did not work at all! This is a mechanical connection and must be maintained. There is a photo of this cleaning procedure in the article “Basic Guitar Maintenence“. There is also a video about this on the video page titled “How To Clean a Guitar or Amplifier Jack”.
