okay, so I have a highway one jazz bass, and i want to install a series/parallel switch, a three way switch for my pickups, and a master volume knob. I've already put in some pickups from an old "cameo" jazz bass copy and some medium gauge flatwounds on it. i don't know which pieces to buy and i'm not sure how i'm supposed to wire both switched up. also, i do not know if i should get a push/pull pot or a switch.
