For the X-Fuzz you'll want to reduce the Pregain pot and the 1M pulldown resistor, with the Neptune Delay you can only really reduce the 1M pulldown resistor which will reduce the maximum input impedance and so may do the trick.  The Rous input impedance is around 500K based on the pulldown resistor and 1M resistor to vref, so just drop those two values down to whatever you want.  So if you used two 100K resistors the input impedance will be around 50K.

For the AD100, reduce the 510K to vref resistor after the input cap.
