Another Warwick Active/Passive Question

    Hi everyone, I did a search for info on this but I was still unable to answer my question.

    Basically I want to know if a Warwick Thumb 5 Bolt-on will switch to true passive mode when the volume knob is pulled....that is work without batteries. And if it does work without batteries does that mean the bass output is in hi-impedance mode? or would it still be in low-impedance mode?

    Here is all the info on the bass in question:

    Schematics: http://www.warwickbass.com/schematics/sch_images/thumbbolton.pdf

    Thumb Bolt-on, MEC Active J/J, MEC Active BEC II, 2-way

    From the owner's manual:
    5-string: 2 active MEC Jazz pick-ups.
    Push/Pull Volume Control (Part #M84500 - 500K)*
    *By pulling on the volume knob, you will bypass the onboard active preamp, which effectively deactivates the tone controls.

    Thanks for all your help.

    The pickups are active.

    It will just bypass the active preamp but the pickups themselves are active so it won't work without a battery. It should put less strain on the battery if you're not using the tone controls.
