I got a couple of single coil pick ups for pretty cheap and now I’m trying to figure out if any of them are “reverse wound/reverse polarity.” I am going the easy route and assuming if they are are reverse polarity, then they are reverse wound. What does that mean? Well, as I understand it, if two single coil pickups are reverse polarity, then when you put them face to face they will attract each other because they are opposite polarity to each other.
If they are the same polarity, then they will repel each other.
But if you are only worried about the 60 cycle hum, apparently the polarity doesn’t matter. The wiring is what must be reversed. This can be done with the lead wires coming out of the single coil pick up. But if you try to make the switch right where the lead wires attach to the volume pot, then you are probably opening up your signal to something you don’t want because you just turned your grounded shield into the hot signal wire. That can’t be great. But I haven’t tried it, so I really can’t say one way or the other.
If anyone has tried this lead wire switch, please comment. Inquiring minds want to know!
