OK, you can't mess with the input cap on the Fuzz Face. I tried several workarounds to change the input impedance, but it kind of stops sounding like a Fuzz Face the farther you get from the original circuit. And not in a good way, IMO.
Here you can see I've gone back to a 2.2 uF input cap, although now a ridiculously overkillified 250 volt cap. And it works like it should again. It doesn't care if it's a polarized electrolytic (my first guess, since I was using a non-polarized .68 uF), but it does want a certain amount of input impedance. Essentially it wants what goes there.
Now it makes more sense to me that Analog Mike builds those Sun Lion pedals that combine a Rangemaster and a Fuzz Face in one pedal. Those two were built for each other.
