Check your guitar cord, try a different one. Make sure your amp is grounded (power supply.) Could be a ground problem in the guitar or a dirty pot. Make sure the output jack on your guitar is not loose. Clean the guitar's switches and vol and tone pots (contact cleaner.) Try each of these steps in sequence. Even if it doesn't clear it up it may help you track down the problem.
