So I was playing my guitar then suddenly the amp started making a loud humming noise. NONE of the knobs seem to lower the loud humming. The funny thing is that a few seconds afterwards, it started to smell funny. It wasn't a burnt smell but I could smell it. Apparently I was the only one that could smell it because my dad said that he couldn't smell anything. So yea... I'm not a guitar amp savvy but I'd like to know if there's a solution and more importantly WHAT IS the solution for the amp to work. Any help is appreciated.
