signal switching help (CMOS or transistor?)

[alparent]

I'm working on a switch box.
My setup is this an Arduino that feeds a 5v signal to transistors that switches 9v to the cd4066 gates.

But I'm also finishing a Equinox Reverb and noticed the signal switching transistor.

I'm wondering If the cd4066 is really needed in my switch box? Could I just use transistors to switch the signals?
Would that prevent any cross talk?

Or is 5v not good enough to switch a transistor passing audio signal (some issue as the cd4066)?

Don't know if this makes any sense?

Use the 4066, Alain.  The "switching" in the Equinox is simply shorting of a signal.  Your switching box has to do more than that.
