Conrad / Apollo Buzz Box & Volume Expander - schematic fix

[Rob Strand]

The other day while poking around with some old 60's fuzzes for this thread,

I realized the schematic kicking around for the following two pedals has an error.  The schematic shows one less resistor and one less cap than the PCB pics:

After a bit of research and tracing I managed to fix the schematic,





These units are kind of like a two knob version of the (3 knob) UMI Buzz Box & Volume Expander. 
Lucifer's trip has a corrected schematic for this one,



You can see one of my fixes to the Conrad/Apollo follows Lucifer's trip's fix for the cap connection.  The other fix, which explains the missing cap and resistor, makes the Conrad/Apollo like the UMI with the Contour control set to one extreme.
