The Switching Scheme

Under construction. At the moment I'm debugging an annoying "click" when I switch between channels. When I kill it (or when I convince myself that it is not so annoying) I'll post it. I've tried using transistor drivers with a "miller" capacitor to ramp the switching waveform (like in R.G.'s latching relay crcuit) with no success.

The LEDs show which channel is active. If no footswitches are plugged in the FS jacks, the ON/OFF/ON switch in the front panel selects one of the three channels. When using footswitches, leave the front panel switch in the "Green" (OFF) position. One footswitch selects if the active channel will be the Green or one of the others (Yellow or Red). The other footswitch chooses Yellow or Red when the other footswitch selected "not Green".
