Sure @Ginsly . D100 is a polarity protection diode. I personally know I am powering my breadboard the right way, so that's why I exclude it. In the schematic, LED and R100 are only for the power on indicator and I don't need that to make this circuit work.
Great stuff here, Chuck. CMOS chips may be worth a Boneyard article to understand how the inverters work and why the topology is different than, say, an inverting opamp. I know I would be interested in reading about it.
Dirt pedals I get when it comes to troubleshooting. This one I don't. I did the Phase 45/90 mod which I think comes standard on the Xc Phase sold here.
I get a horrible oscillation/whine when this pedal is engaged and there is also distortion, which is a big no-no for this. In the Phase 45...
Considering the part count, it may be worth your while breadboarding this and modding to your taste. If it helps there's a nice breadboard tutorial on it.
