buzzing sound

[bf0502tr]

hey anyone here ever went for electric guitar courses in yamaha before? their amps work quite differently from one of the low end ibanez amps i tried at swee lee. at yamaha, there wasnt any buzzing sound when the strings were left untouched on overdrive but the amp at swee lee had this buzzing sound. the guys said i had to mute the strings but i noticed in yamaha i didnt have to touch the strings at all. anyone know wat this causes this buzzing sound?

grounding issue?

new amp may comes with a 2 pin plug.
change to a 3 pin plug will help
