I've just got the front Single / rear Humbucker Telecaster. It is normal 3way blade switch volume and tone. So I want to mod to 4way blade switch with 1 vol/1 tone push-pull split wiring(rear humbucker) I've looked for the web but have no chance to find one. I've done several wiring with this helpful Duncan site. Is anyone knows how to please share with me. I have soldering iron but no multimeter and not know much about the electric circuit. Thanx
