    Hi all...
    Why, do you all think might I be encountering the following;
    When the tone of a '51 style P bass is all the way open, the bass is quiet. When it is rolled all the way back, it hums, unless I touch the strings.When i do, it stops humming.
    My guess is that there is an earthing issue somewhere. What I do not understand is the difference, depending on tone knob setting.
    What might be the reason for this?
    This is a passive single coil-equipped instrument.

    Thanks!:)
