Diagram for series wiring in a Telecaster. This setup uses a push pull pot and an additional capacitor to enable HOOP (half out of phase) and series wiring.
The advantage of this setup is that it uses a push pull pot to achieve neck and bridge in series, rather than using a 4 way blade switch. Additionally, we can use this setup to switch between series and out of phase wiring.
Regarding the below diagram, it is wired for "out of phase" when the push pull pot is activated in position 2. If you prefer HOOP (half out of phase) then simply replace the connection in red on the tone push pull pot with a 0.01uF capacitor.
