Hi, I'm refinishing my very first bass and it's time to put new electronics in. This particular bass is a PJ configuration with a 3-way switch. I'm decent at soldering so that's not an issue, the issue is of knowing which wires go where. Looking at the old electronics I pulled out of it it looks like the pickup wires each go to a separate tone knob. The black is the ground and gets soldered to the base of the tone pot while the white one gets soldered to the middle terminal. Is that correct?
