my marshall avt100 functioned fine up to a couple months ago when it developed a buzzing sound.
the sound is not present unless there is an instrument cable connected.
when you do connect an instrument, or just the cable, the buzz appears, becoming louder in the od1 and od2 channels.my suspicion is that a mishap with an idiot tripping over my instrument cable caused damage to the input jack of the amp and now the pin of the instrument cable isn't contacting properly with the jack.
ANYBODY AGREE OR DISAGREE WITH THIS EXPLANATION.
I'm getting a new guitar 2moro so i'd appreciate help in fixing my amp.
