I have to laugh about this after reading such lines as “Are ALL Opus 3s broken?” all over this board. Mine is for the most part pretty solid, save for a couple of issues. I’ll address them one at a time.
Most aggravating is the noisy output. All I have to do is have it plugged in to any amp or mixer/PA setup and it hums like a son of a bitch, at any volume level. Are they just inherently noisy or does it need a closer look? A grounding issue, maybe?
