Here's my corrected layout:

Finally I'm building this.
I have some question. I probably gonna use a 125B box, so none switches.
But, for an eventually next time I would to know what those switch do.
I got this:
- First switch to choose the input cap 4.7nF or 10nF;
- Second switch to choose the coupling cap 470nF or 1uF;
- Third switch to choose the clipping sections, Yellow Led or Red Led;
- Fourth Switch to choose the output stage. To do what?

Thank you!
