Can this pickup http://www.seymourduncan.com/products/bass/soapbars/5string/passive_phase_i/ be wired with a single jazz pickup? I would like to put one of these in the "sweet spot" and have a single jazz pickup between that and the bridge. Any issues to look out for? Both would be passive. Would prefer a blend pot as I like to do volume swells with a master volume knob. I'm not finding much on diagrams for this. Any help is greatly appreciated.
