    Anyone using two amps?
    How do you split your signal?
  2. You need to have two cabs before you try a signal splitter.

    Bass -> BigMuff PI dry output -> WahWah -> Amp 1
    Bass -> BigMuff PI effect out -> several other effects -> Amp 2

    Amp1 is set up as a common amp, amp2 has a heavy low-cut

    When I've done it in the past I took a line level output from one rig -- either an effects loop send or a dedicated preamp output -- and fed that into the power amp input (or effects loop return) of the second rig.

    I've done it in the past using a voodoo labs amp selector. Granted, I had two heads, and two cabs.

    I split the signal at my MXR M80 DI. Regular 1/4 out to one amp and parellel out to other.

    Are you talking about 2 heads to one cabinet, or two complete rigs / combos? If it's the latter, I use a Radial Big Shot ABY. It has a isolation transformer to kill the hum and a phase reversal switch as well. Built like a tank.
    Radial also makes the "Headbone" switchers, which enable you to use two hads with one cabinet. There are separate units for tube or solid state amps. I don't think you can mix the two types.

    There are many ways to go about this- stereo fx pedals, buffered AB/Y box, a mixer. Tell us the goal, and we can tell you the best way to do it.

    You could make your own passive splitter with an audio isolation transformer.
    Document AS103 shows a drawing of a simple passive splitter here:

    The load, and more importantly the capacitance seen by the instrument is affected by connecting two amps, with just a Y cable, so the addition of an active unity gain buffer amp is used in most commercial splitters.

    If you're running two separate rigs, and one has two inputs (passive and active/ 1 and 2), just run a jumper out of the one you don't use over to the input of the other amp.

    Yup I have the Lehle P Split for when I use two rigs. It keeps my two signals absolutely noise free, as I was getting hums trying any other 'cheap' way (slave out, fx loops, chrous pedal, morleyABY).

    Jazz out into buffer one line into effects. into mb200 into 2-12 cab. Second line into. Biamp m2v xover output of xover into bgw power amp into 12" sub 100hz and below

    This is what i have landed on after my experimentation. Going for a lehle splitter

    Good choice, Lehle is pure quality.

    my bass goes into the wha then over to the chorus with sterio outs one side goes straight into my gk rb700/neo410/115(cleen side) the other side goes into the 3 channel programmable sansamp then out to a hartke ha3500/swr 2x12(dirty side).
    i can use the level controle in the sansamp presets to adjust how much dirty side i get from the hartke while the gk stays clean so i can have crunchy distortion and still have good definition to my sound
    the cleen side is soon to be replaced by a gk mb800/fearful 1212/6/1, i'm not shure yet if i will move the rb700 over to the dirty side or keep the hartke and i might replace the swr 2x12 with a fearful 12/6
