    Hey all ...HELP ! 1978 Marshall 2204 .. head. Full stack 1960 4x12 CAB’s (2x4 12”s) how do you connect ? Set amp 4 ohm & cabs 16 mono ?
    1. ampmadscientist
      The amp must be set to match the cabinets.
      If you have 2X 16 ohm cabinets, the amp should be set 8 ohms.

      I just might have to put the DSL on hold n get the Code with the cab n give it a whirl.. Than maybe get the DSL. Be easier on the bank @ first

    Hey man, really hope you're still active on this forum. I want to make a Youtube video about Marshall 2204 amps because there is so much bad (wrong) information about them all over the internet. Of all the forums I have visited (a lot!) you seem to be the most knowledgeable regarding these amps. Would you mind me asking you a few questions just to make sure I have the facts correct for the video?

    Absolutely perplexed that you dont know were hiss/noise originates from, or how to minimize it. Aren't you an EE ?

      Noise / Hiss in guitar amps is rarely discussed or studied.
      I'm trying to bring the subject out in the open....

      It is my hope to develop high gain guitar amps which rival noise levels of hi fi amps.

      By doing this - I hope to change the industry over to a higher performance standard.

    What you hear is that patch cable acting as an antenna when you don't plug a guitar. It picks up interference in the air.
    1. ampmadscientist
      I absolutely agree.
      "Antenna" is the perfect description.
