    I'm playing at school friday which is also the day I get my GK 400RB IV in the mail. I just learned that the whole band is going straight to the PA and I was wondering if it would be ok to bring the head but only use its line out. I wouldnt be plugging the head into a cab or anything. Would that be possible or could I damage my head that way?

    Depends on the amp, actually. Read the owner's manual and find out. You should be able to read it online before Fri.

    You probably can, but you will not be able to hear yourself very well. Bring your cab.
  5. I'd be careful with it, some amps can handle it and some can't. If you do it, make sure you have the master volume all the way down.

    The best idea would probably be to bring your cab and use that for your stage sound and send the line out to the PA for the FOH sound.

    the GK 400 rbi IV should be able handle no speaker loads fine. my RB III can, according to the instructions. In any case, like someone said, u can just turn the master volume all the way down and it wont affect the line out signal at all

    If you must go into the PA without being able to use a cab, why not just bring a DI box?? It sure beats having to lug an amp around just to use the line out......

    yes it will work IF they have a channel on the snake that will accept your 1/4 line out plug OR if you have an XLR direct out from your head AND if they have a channel on the board free AND if the PA speakers can handle the bass guitar signal AND if the poweramp for the PA is powerful enough to do it.

    But, all this may not fall into place, and like others have said, this still leaves you with the problem of being able to hear yourself.

    well, im going to just use a bass combo the school has. Thanks much for the replies. one more thing: Why is it bad for the amp to go direct lineout instead of hooking it up to a cab and lining out as well (scientifically speaking)?

    I've heard that before. "Everything is going through the PA." Except when you get there you find out that there is no line out jack on the guitar players Marshall stack or on the keyboard players Leslie speaker so they both have to have a mic hanging in front of them. And to get the right sound they have to have their rigs cranked up real good. Take your head and your cabinet.

    it isnt. people do it all the time.
    the point is, unless the pa is good enough to handle your bass and has monitors that can handle the bass and enable you to hear yourself you'll need a cab.
  12. Some amps, generally older models and/or tube amps, will blow a transformer if there is no speaker load while the amp is running. Most current solid state amps are immune to this as they have protection circuitry built in. I'm not sure if tube amps are in the same boat nowadays?
