Assembled my new frankenbass, a P with Dimarzio model 1s at neck and bridge, no p pickup. My other P has a J and I've put in a switch so I can switch it from normal output to stereo, with a pickup to tip and 1 to ring. This time I've tried to do the same but with tone pots in addition, and a stacked volume, so I can turn both down easily. However, its not working like I want it to and I don't understand, How should I be wiring this? Is it the tone pots bleeding the pickups into eachother? Is that why there are reisstors in a stack knob jazz? Do I need to use a switch with dual poles rather than a single? Someone wanna draw me a diagram that will work? I don't understand this.
