recently purchased two EMG soapbars for my Schecter along with a BQC control set. After installation I have two sets of Volume and Tone Controls that came with the pickups just laying here extra. Also have an extra battery connection and several extra jacks. I have an old Rogue 4 string bass that has two simple split p pickups but no controls. The volume and tone pots that I have from EMG have soldering or plug in connections. Wondering if I can use the EMG volume and tone pots with the battery connection in this rogue or not. If so..how to wire? Have looked up several diagrams but nothing seems to be what Im looking at. one of my pickups has a black wire coming off and one has a white wire...there is a blue wire connecting them.
