Any chance the Mofeta schematic will be published soon? I've been thinking about getting it for ages now, but I like to map out what mods I make before I purchase a PCB.

Okay, I'm completely stumped by this one. There is no power anywhere on the pedal except through the first diode, D100. Then, there is no voltage on either end of R100 even though there is continuity from D100 to R100! It's the same for pin 8 on all the ICs, continuity to power source, but no...

Not sure if this is too late, but half supply voltage is applicable for trimming JFETs. Since the supply is 18V due to a charge pump, measure about 9V on each JFET Drain. Look up "J201 pinout" to find which pin is the drain. Hope that helps!

Nostradoomus, the legs aren't shorting. I spread them out wide, and still no voltage on either. Chuck, I will look into that! Other people have verified the circuit with C16 being polarized here, so I'll try keeping it for the time being. Sounds like I need to order some 4558 chips. How come a...

Here's what I got for now, I suspect I misplaced a resistor. Thanks!

I'm nearly done with my Pitch Witch build, but I'm stumped on getting the LFO up and running. Here are the symptoms: Delay part works perfectly, but neither LFO or indicator LEDs are lighting up. I also think my dual op-amp chip is heating up a bit, and I switched chips to no avail. I used...
