Amp problem

Try it in another room on a different power circuit. If that doesn't help, try the amp at a different house. It can be due to outside interference such as a fridge or air conditioning motor, fluorescent lighting, light dimmer, or line noise. Even a bad transformer out in the street is a possibility. You need to rule out if it is the amp vs the environment.

Just to be sure, check that the nuts are tight on the jacks on your amp. A loose nut could be causing a bad ground.
