I bought the Marshall code 100 Head as a second hand after watching the positive reviews of it, and I really liked the sound and its features!
I plugged it to a 1 x 12 Cabinet and it works good except for my big disappointment with the hissing white noise that i was getting even when the master volume knob on the amp is turned all the way down.
I tried every simple solution that i could come with, including turning off the computer in the room, I tried resetting the Amp to factory settings, I even installed the new firmware from the marshall website. but none solved this issue.
Does anyone know the solution for this problem?
Thank you very much in advance
