My new CODE-100 2x12 has a prominent digital fizz noise it also crackles, very unpleasant specially when you use tremolo, chorus, delays.
Very noticeable on the decay of the notes, decay of notes crackles.
When you play the low E string unfretted it makes a buzzing noise, this is difficult to forgive in any amp.
Are you guys at Marshall aware of this? should I return the amp?
