Morley Power Wah Fuzz. Fuzz only.

The link goes to the Telray Power wah/fuzz.

Every time I try to trace just the fuzz portion, I get lost.
It's sort of annoying. Really annoying.

If someone out there is having a slow day at work or is bored, can you please isolate the fuzz portion?
I could put the entire circuit together and leave the wah in a permenant off position, but that would be such a waste.  (Besides, if I did that I would just use the pedal as is.)

It's actually easier to isolate the wah part and remove everything that isn't that.

R24 is where the wah part starts.
Q2 and Q5 are the wah's transistors.
2, 3, and the part with the LDR are part of the wah, so you can remove those lines.

The fuzz is also controlled by an LDR. Morley loved their LDRs ... that's the thing marked "5".

The power section to the right can all be simplified. You just need standard power filtering and polarity protection. You can duplicate the original effect by knocking the voltage down to 7V with series resistance and/or an LED (1.7v Fv drop + a 100R would put you really really close).
