Sounds like you need a tech to replace the power supply caps (all electrolytic caps actually).

Make sure your power cable has a ground pin that's properly connected. If you are too close to the amplifier all basses will give you hum to a greater or lesser amount. Failling all that follow Mr. B's advice.

Try a different outlet- the one you're using may have a problem. Is the instrument cable plugged in? Do your lights have dimmers instead of On/Off switches? If so, turn them off and see if the buzz goes away.

Also make sure there aren’t any tube lights, electrical motors (refrigerators, pumps, etc) on the same AC circuit as the bass amp and make sure the AC outlet is properly wired.
