    can you play thru 2 combo amps at the same time??
    if so, how???
  2. yeah,
    If one has effects loop in and out jacks on the back, then take one, run a cable from the effects in on the first one, from the input jack on the other (i think...) and then turn them both on and plug into the one that has the bass input jack unoccupied....
    I dont know if thats exactly correct with the in out, but it shouldnt hurt your amp to play around. Just remember, effects loop on A to one of the jacks on B and you plug into A, but keep them both powered

    There may be several ways to do this, depending on the inputs and outputs on the amps, but the easiest and most universal way would probably be with a Morley ABY switch.

    My freind tried that with his 2 Marshall 150 watt ers....needlesss to say he did something wrong and now they are useless:)
  5. Don't tell me he fed the output of the first into the input of the second? :(

    As Slater said, there are several ways depending on existing inputs and outputs.

    But there is ONE way you should never try: connecting the second combo to the 'ext. speaker' jack of the first one.

    Basically, one combo needs a line level output (if you don't want to use some kind of signal splitter).
    This can be 'effect send' or 'pre amp out' or 'line out'.
    You can connect this to the instrument input of the second combo. (Or to the 'effect return' or 'pre amp in' if available)

    My friend Rob uses 2 SWR Redheads for his rig. I think he utilizes the effects loop.
  8. Hi Kirby.

    There's only three ways I'd consider.

    1. Effects loop.
    2. Small mixer.
    3. A/B box.

    ok, a/b box is out of the question, b/c i want both booming at the same time :p

    now, how exactly does the "effects loop" method works???;)

    Decide which of the two amps you like the tone of better. This is the amp you should use as the master. You will control gain, EQ, etc from this amp.

    The second amp will be the slave.

    Using a regular 1/4 cable, locate the LINE OUT on the master amp. The may be labled "lineout" or perhaps "preamp out." Any decent size combo will have a line out. Run the cable from this to the EFFECTS RETURN on the slave amp.

    What you are doing with this method is using the preamp of the master to drive the power amps and speakers of both amps. It is completely safe to do this.

    DO NOT attempt to use any 1/4" port labeled "speaker" or "ext" or "extension" to connect the two amps. The effects return is only designed for a line level signal.

    This method gives you the best control over your sound.

    You will still probably adjust the volume of the slave amp using it's master volume.

  13. I use 2 combos. I have a Chorus pedal with 2 out puts. I just run cords from each out into each amp's input, not the effects loop.

    Thanks for the extensive description Chasarms, that made it really easy for me to understand :D thanks again for that ;)

    And Nomadic Herder, so what you saying is, say I have a chain of effects(which I do) and my last pedal in the chain has 2 out puts, I can just take 2 cords and send them to the amp's main input and that would work also??? :confused:

    Yes. That would work fine. NH's chorus pedal is probably stereo so the two outputs actually are stereo and the two amps create the stereo effect.

    If you did it like that, you would control each amp absolutely independantly, which may be good or bad, depending on what you want. With the method I suggested you could have tone control over the whole rig at one amp.

    Either way will work fine.

    Get a Sansamp Bass Driver D. I. pedal. Run the output of the Sansamp(with the desired amount of overdrive) to the input on one amp. Run the parallel output of the Sansamp to the input on the other amp to send an unaffected
    (clean)signal . (or just get an A-BB pedal)
