    Hi, I recently got an old 100 watt ampeg bass head and it makes some noise. Like the fan seems a little loud or something... is this common for heads and does it make recording difficult if im using a cardioid condenser mic?
  2. I can't imagine that the fan is loud enough to be heard above the amp when you're actually playing? Sure a mic would pick up some noise between gaps in playing, but that's what a noise gate is for.

    oh I havent tried recording yet, i've got a microphone on order and i want to try micing the amp instead of going directly to the recorder. also... how bright should 12ax7 tubes be? very faint orange or should the whole things glow?

    It shouldn't be a problem at all if you just move the head away from the cab. This is what I have done whenever I need to record. Get a good length speaker cable and just leave the head on the floor or a stool or something.

    Very faint, if they're glowing alot, then either there are LEDs behind it, or something's seriously wrong.

    It totally depends on the amount of voltage the circuit designer has going through it.

    I have had tube guitar amps that the preamp tube barely lit and others where the tube had a nice, orange glow to it.
