Capitalist Death Cult Just. Give. Up. V2Verified

From the post

Another contribution by Chris. This time he made some improvements and addons on a rare and wild Death by Audio circuit. Tone houndz...stay away! Chris says: I don't know if this warrants its own post but I wanted to show it to you anyway since I was the one who verified your purple card drawing.

Since I built that up I wasn't happy with the bleed through in bypass that sometimes happens with the LM567. So I used the old "millennium bypass" trick of adding a mosfet to handle the LED switching so that you can use only a DPDT for true bypass with an indicator light. THEN I used the now-vacant set of poles on a 3PDT to connect/disconnect the power supply to the LM567 when the circuit is bypassed. So NO NOISE! I also added the master volume, because if ANY circuit needs it, it is this loud beast. Then I put the frequency pot (which I cut down to 10k) on a switched expression jack so that you can get foot-controlled crazy pitch-wah sounds with a standard TRS expression pedal like an inexpensive m-audio or nektar controller. Anything more than 15-20k of resistance for the frequency control just takes you into slower and slower chopped/tremolo territory. And the 10k pot still allows for some of that in the toe up/CCW position and all of the pitch control as you turn the knob up/put the treadle down.

I added a toggle to change the resistance on the frequency sweep - this allows for a low range and high range mode on the frequency. Since most expression pedals have 10k pots, I wanted to keep the frequency pot at 10k too so that the sweep matches whether you are using the knob or an exp pedal.
