Pre/Post Circuit Switcher Diagram?

[Jazzman]

Not sure if this post should be in the tech help or mods section but here goes:
Just wondering if anyone has seen a diagram for installing a circuit pre/post switch so for example, you could place a boost circuit in front of an overdrive for more gain or after it for a level boost???
Cheers guys!
