    Welcome to TalkBass!!!!!


    I'm reeeeeeeeally glad you came here and asked before you did it.

    Ok, so, you can't do it on the power end at all..... period. You can NOT daisy chain the power sections.

    What you can do is use two of them as a "slave" amp with the preamp of the third driving all three amps.


    Which one do you want the sound of? What kind(s) of cabs are we talking about? What's the goal? What's your level of experience when it comes to electronics and such?


    I'm NOT bashing you. We need to know a little more before we can help.

    Take the "effects send" from the master amp to the "effects return" of the first slave then do the same from the first slave to the second slave.

    You can go preamp-preamp-preamp-power-cab via the sends, but what is that going to get you?
    You can only use one power amp into the iso cab at a time.

    Noooooooooooo!!! You can NOT run all three power sections together into one cab. Period. Smoke will come from everywhere!!!!

    Do NOT run three heads into one cab.

    Nope.

    Don't.

    Stop.

    Please give us even more detail of the setup you are trying to run (and why).

    I don't want you to fry your gear.

    Just a preferred setup so I can use other speaker cabs and an isolated at the same time and run the iso to more cabs, moral is, I have a lot of cabs

    Since its not my gear, go ahead. Good luck. Make sure you have a fire extinguisher handy.

    I think what the OP wants is a selector box that allows various amps and cabs to be interconnected. Select the amp and cab you want to play instead of repatching the cables every time. These are not common, but I have seen models by Ampeg, Trace Elliot and Gallien Krueger pop up on Ebay from time to time. I believe they are basically intended for music store showrooms. Here's an example:
    502456d1443973009-speaker-switcher-guitar-cabinets-54100488.

    Some variants even allow you to select two cabs at one time...you would be wise to be mindful of the changing impedance and the load your amp expects.

    I just tried connecting the effects sends and returns and ran different cabs from each head and there seems to be no fire.

    You said you wanted to run them all into one iso cab.

    Again, I have way to many cabs, and it would be a waste not to use all of them

    Absolutely.
    Please tell us about what happens when you plug all three amps into the one iso cab at the same time.

    Here's a rack mount device that allows you to "Safely and silently switch up to 4 amplifiers into the same cabinet or load device!" Custom order and it's not cheap.

    Ah. That would almost make sense if two of them weren't the same amp. Wonder what the point is....

    Im trying to kind of replicate paul grays old setup (R.I.P) Because he used two power amps to run multiple cabs and used one normal head to run an iso cab

    I got confused about your goals. Hope you get it all hammered out. Hope I didn't offend. I thought you were running three amps into one cab at the same time. :D
