    How would I go about sending a signal through two different amps with a crossover? Is it possible to send EVERY frequencies through my Gallien head while running everything in a guitar's frequency through a Marshall half-stack? Do I need anything besides a crossover?

    Is a Behringer CX-2310 Super X Crossover any good?

    It can be done but you'd have to split your signal in two before the crossover. The cheapest way to do it is with an A/B/Y box. Set it to "Y" mode, send one of the outputs to the GK, and the other to the crossover. Leave the crossover output for lows vacant, and send the highs to the Marshall.

    I wouldn't be surprised if there was some kind of a thru output on the crossover that left the signal untouched. In that case, you could use that to send to the bass amp and avoid the extra box.

    Use the Effects loop send or the DI out if available on the Gallien to feed the X-Over, send the hi-pass side out to the Marshall. While this will work 'electrically' I suspect that from a tonal perspective, it will be a short lived experiment however you accomplish it ... watch lo low freq cutoff on the X-Over. You don't want to get too low or you're going to punish the driver's in that half stack ...

    If you need a small cheap single channel Crossover, you might take a look at the rolls SX-21.

    Rolls SX-21 description and manual:

    Typical online pricing:

    I like it because the frequency can be set as low as 50hz. This works well for many 4x10 cabinets that only have a frequency response down to the 50-60hz range.
    Many crossovers in Bass preamps only go down to 100hz (if even than low).
    Many of the lower priced PA rack crossovers also do not go down to 50hz. Some PA rack crossovers only accept XLR inputs and only provide XLR outputs.
    Besides, why waste an entire rackspace when you can get a unit the size of most effect Pedals.
