Hey. I'm going to put a series/parallel 3-way switch on my jazz bass. There are several diagrams online showing how to do this but they are all for 2 way switches. I want a 3 way switch where the middle is a kill switch (an off switch if you will): Up pos - Series Center - Off Down pos - Parallel I assume I need a DPDT with a wire for the center position grounded or a DP-Center off switch. Not sure what the difference is. Help is appreciated.
