I just traded some stuff to a friend for it, plugged it in, and was like, "whats all the hissing from?" Of course I do have a bright setup, and it was more noticeable in my AC30 than my Fender Deville. I also read that there are no noise reduction circuits in it whatsoever because Bjorn wanted the decays to sound as natural as possible. And the decays really do sound amazing, but I for one could do without the noise! Any thoughts?
