I need help rewiring my jag bass. I want to add 2 stacked pots for independent vol/tone for each pickup instead of master vol. tone. From the stock diagram you have a hot lead running from the 3 slide switches to the master volume, you also have a single wire from the active passive switch running to the master volume as well. So my question is, how would I rewire so I have 2 leads coming from the slide switches to each concentric pot and what should I do with the preamp lead going to the master volume? Any help would be most appreciated. Thanks.
