I may be getting easily confused in my old age but... I just wired a Les Paul from scratch and I think I've seen wiring diagrams show two different ways of wiring the three-way toggle switch. Some show this: Ground tab = between the two tabs that go to the neck and bridge volume pots. Output (to jack socket) tab = the tab on its own on the other side of the switch. And some seem to show it the other way round. Please, someone, put me straight! Which way is right?
