    Hello !

    I'm using a MIKE POPE Flexcore 2.2sk and this crazy noise just appeared !


    This is too crazy for me ! LOL !

    When I'm plugging the bass, if I just put the half plug inside the jack starts a crazy noise like a diesel motor ! LOL ! But when I plug it 100% this noise just stop ! Do you know why ? It wasn't happening before ! In passive mode , it's ok !

    Crazy !

    Any thoughts ?

    The first question is why are you plugging your bass in with the amp turned up? That's a great way to damage your speakers and annoy your neighbors/audience. Just plug your bass in first or at the very least turn the master volume on your amp all the way down when plugging/unplugging and you should be fine.

    Yes you right ! I always do like you said, but this bass (withe POPE pre) is the only one that emit this strange noise when half plugged !
     
  4. Why would you expect it to sound normal when half-plugged in?

    The Flexcore uses a different scheme for disconnecting the batteries when unplugging the jack than most preamps. Most of them simply run the negative battery voltage through the Ring and Sleeve of a TRS stereo jack, but the Pope uses that connection as more like a relay. The voltage itself does not flow through the jack, it's just a switch. So it should behave differently than other preamps when that switch is half-activated.

    In a nutshell, stop doing what you're doing. Plug your bass in quickly and fully and THEN turn your amp on.

    Thanks for the answer ! I expected it because the other basses that I have do not emit this sound ! Too strange ! But when it's 100% plugged the bass sound is great and normal !

    Many thanks !

    Most gear made for bass is designed so that it works properly when the cable is fully plugged in.

    :D

    I say keep doing it until you blow your speakers then the noise will stop I promise.
