I'm having a very hard time believing this is correct. The "b" section of the opamp is a filter. How will the input signal get to the opamps input in the "hi" setting?

And google t-filter or look at a morley wah (not the bad horsie, that's a crybaby) to see how to draw that filter in a more readable form. (hint: give that opamp a vertical flip)
Sorry. Plain out of planes.

:D

I'll draw it as the Dr Q; more readable! I noticed that the writing on the side of the trimpot / potmeter in this unit was NOT the value; so that B223 was NOT the value but the value underneath the potmeter (B503) was the real deal! I'll change that one too!

awesome bro, i love this circuit.

i worked up a "daughterboard" for it for the tagboardeffects layout, figured i'd share it here.

basically its an effects loop for the pedal ;)

the dr quack buffer from jack orman, and a little darlington boost stage i worked up for it cuz it was way below unity when i built it.

its small, a 7h x 5w piece of vero ;)

hope it helps someone, i love this circuit, its a lot of fun.
