    Hey all, just have a quick question regarding my 1200s (the rackmount version)

    When I turn the power switch on, a small pop can be heard from my cab a few seconds later. This happens every time.

  2. is that with the volume and gain all the way down when you turn it on?

    Yes, it will happen regardless.

    It's probably normal. There are several turn-on mute circuits and a relay that disables the power amp in the event of over-temp.

    It does on my Bassman 1200, which is basically the same thing....with a different name.

    Okay, if the Fenders are doing it too then I'll assume its in the design and not a problem.
