    Both my other left-handed guitars use conventional pot wiring: ie, clockwise makes it louder.

    The wiring on the JB is not standard pot wiring anyway.
    With a normal volume control, the signal source (ie pickup) is wired across the two outermost pins of the pot, with the shield connected to the "anticlockwise" pin. (Anticlockwise looking at the knob side). The amplifier connection is taken from the centre (wiper) pin, with its shield also soldered to the anticlockwise pin.

    In my Bass, the pickups are wired with the signal ("active") wires going to the wipers of the pots; on the pot for the bridge pickup the shield wire goes to the "anticlockwise"pin, and the signal is taken from the clockwise pin.
    On the pot for the other pickup the shield wire goes to the clockwise pin, and the signal is taken from the "anticlockwise" pin.

    I know the reason for connecting the active signal wires to the wipers; because there's no selector switch, if they were wired in the conventional way, turning down the volume on one would also turn down the volume on the other.

    I really just need to know if swapping round the output and shield pins was intentional or not. I can easily re-wire it.
