Ok I've had a look and things don't appear to be right.. But I could be very wrong..
There is a black wire and a white wire coming from each pickup, but both black wires go to the neck volume knob, and the bridge knob just has the white wire from the bridge pickup and the white 'bridging' type wire from the neck knob to the bridge knob.. Does anyone else have a MIM Jazz to compare the wiring??
Thanks guys
Matt
