    Why does my Marcus Miller Jazz Bass still need a 9V battery in passive mode?

    I always heard passive basses don't need a battery
    I gotta say mine is supposed to be both but if I remove the battery, it's goodbye sound :eek:

    Some require the battery for the circuit to work, even without the pre engaged. IMHO that`s a design flaw.

    QC flaw

    My very first black Reggie Hamilton (now I got the 3TS one) had this funny issue:
    #1 active/passive switch on, equalizer on, volume on, active expected output;
    #2 active/passive switch off, equalizer off, volume on, passive expected output;
    #3 active/passive switch off, equalizer off, volume off,
    passive expected output.

    I played full gigs with active/passive switch off (passive mode)
    with volume full turned down (I'm serious)

    I gave to my tech, not for problems, but for the fun of it, and he rewired the failing connection. Reason behind it still playin' was he worked out 18v batteries. They were off whenever my jack was unplugged, they were (the batteries, not the 3 band equalizer) always on, whenever I plugged in...


    Cheers,
    Wallace
