Knobs are made to be fiddled with, and within your practice space there are no right or wrong answers, only sounds you enjoy and sounds you don’t.
Edit to be slightly more helpful: A good place to start on a PJ bass like yours is turn your P pickup to the desired level, and slowly turn up the J pickup to add some of that qwackier flavor until you find something that sounds good to you. Play with the tone knob from there to mess with it some more.
