my amp makes a humming sound, whether the guitar is in or out. it isn't loud, but this my first 100w amp, so i wanted to know if this is normal.

i got a 100 watt that hums too. boss ns-2 noise suppressor will get rid of ne feedback sounds, as well it tells the diff between ur guitar sound and the feedback so it doesnt take away from ur tone at all.
