Multiple AMP setup Ohm question

Discussion in 'Amps and Cabs [BG]' started by unatratnag, Mar 17, 2006.


  1. Saw questions before on this, but didn't find on on ohms. Since i've never tried it before I figure I'd ask before I blew something up:

    I was going to hook bass up to input of amp 1.
    Have amp 1 effects out to effects return of amp 2.
    Then have a cab hooked up to each amp.

    Both cabs are 4ohms by themselves. Will there still be a 4 ohm total load after this setup or due to physics does it come down to a 2ohm load?

    I also assume when hooking up the effects out to effects in since it's still just a regular signal I can just use a regular instrument cable no issue as well.

    And while i'm at it, when i was doing searches i'd find references to "clean signal" and "wet signal". I assume "clean signal" is the unaffected unpowered signal coming from the bass. What's a "wet signal'?

    No problems as long as you run each head no lower than its rated load. Really no difference than using each separately since you haven't changed anything at the power-out/speaker-in part of the signal chain.

    Properly used, a wet signal is what's coming off an effect - such as reverb, delay, chorus, etc - though most effects allow you to work with the mix of wet-to-dry internally.

    The power amp section of each amp head will operate independently...the load on one amp doesn't affect the other amp, they're only interconnected at the preamp level.

    So, in your situation, each amp sees a "4 ohm" load.
