If you go here, you'll find anumbr of octave-down circuits.

Most will combine original and octave down, so in many cases, getting only the octave-down sound is simply a matter of lifting whatever resistor carries the straight signal to a mixer stage.

my old original Octave Multiplexor had a knob to mix straight and octave-down signals......haven't seen it in a long time, though.
