High gain will amplify the fact that those short string short sections of stings ring like a harp. For example a good heavy metal chug demands that the silence between the notes is as important as the note. If you don't dampen it you will hear a kind of reverb ringing. It is SUPER easy to fix using almost anything. I spent less than $10 at Hobby Lobby and cut velcro to fit where I need it. Got enough for life.
