Make an active bass passive?

    Hi all!

    I´ve recently realized that the preamp in my Washburn ain´t so great. So I was wondering if there is a simple way to disable the preamp thus making my bass passive?
     
  2. I'm not an expert, but I think you would need new pick ups. From what I know, passive pickups are different than actives. You would have to remove the active pups and preamp, then install passive pups, and rewire it all back together.


    Of course, I could be wrong.;)

    ...and you probably are :D

    Most basses have <b>passive</b> pickups and <b>active</b> EQ, so it's not a problem to make it passive. But it'll probably not sound better...

    Bleh...

    Then I´ll seddle with turning the Tone pot down on my bass.

    I bought the Sansamp bass driver DI the other day, and when my bass is plugged in, it gives out a very overdriven tone, kinda like using a distortion pedal. I´m guessing that the preamp on my bass is "not so good". But I just found out today that the problem disappeares when I turne down the tone pot, so that will just have to do :)

    Maybe it's just time to change batteries ;)

    Way ahead of you :)

    Already checked the battery, even replaced it, but still the same distortion. But it works fine to turn down the Tone pot. :)
     
  7. I think your problem may be mismatched input voltages or impedences. I know that the SansAmp is popular but I don't think it would be worth it to run an active bass through one.

    The distortion after the battery change is the telltale clue.

    And with that brilliant analysis :rolleyes:, I'm kickin' this thing up to pickups.

    Thanks,
    I wasn´t quite sure wether the post should go in Setup or pickups :)

    But as I said, with the Tone turned down, it´s just fine.
