The Aion version has some changes that aren’t supposed to effect the sound, but are to make it more usable. For instance, I believe it’s modified to use a 9 V power supply, and the dual outputs of the original pedal are combined to a single one with a toggle switch. But those types of things...

Concerning the divider, the Pedal PCB circuit said to use a 150 k and 100 k combination. I found on another forum that a guy instead went with a 47 k and 15 k combination, through trial and error, to brighten up the pedal. Are you saying that the original circuit does, in fact, use the 47/15 k...

That is correct. I’ve edited my post with the correction.

I kind of view it as a solved problem for me personally, but if there is interest from others to see if the circuit now differs from the original trace, I would be happy to take the back off and photograph that side of the PCB.

Thanks for all your help.

Figured it out. I brought up a picture of someone else’s circuit and somehow noticed within 10 seconds that I had the diode all the way in the bottom left in backwards. How I spotted it, I have no idea, but I got lucky and noticed it. That’s why the voltage in the low side of that resistor was...

Unfortunately all of the other resistors between the 100 ohm and the charge pump are what they should be 😕

Do you know if there are any simulations of the Klon circuit where you can probe what the voltage values should be at various locations?

It’s a 5-band, brown/black/black/black/brown resistor, which seems to indeed be 100 ohms. I don’t know, man, the D100 diode right before it looks like it’s getting the 9 V, and the little branch after D100 that contains the LED is getting enough. But on the low side of the resistor, the voltage...

Yeah, measured it again and it was 100.

9 Volts. Here’s something, though. I was wondering why the input voltage to the charge pump was so low, so I was looking at the R100 resistor in the diagram. The high side voltage of that resistor is just under 9 V, but the low side is around 1, which is what I’m seeing on charge pump input...

These are measured with the pedal powered and engaged. IC1 (TL072) 1. 0.454 2. 0.454 3. 0.416 4. 0 8. 0.911 7. 0.469 6. 0.454 5. 0.452 IC2 (TL072) 1. 0.439 2. 0.452 3. 0.453 4. 0.162 8. 0.482 7. 0.442 6. 0.444 5. 0.453 IC100 (Charge Pump) 1. 0.898 2. 0.898 3. 0 4. 0 8. 0.898 7. 0.124 6...

I can do that, but you’ll have to tell me what to measure 😊 I don’t know very much about this sort of stuff. I do have a multimeter, though. I really appreciate the help.

I’ll give it a shot. Sorry if this is a stupid question, but if the jacks need a connection to the enclosure, doesn’t that mean that the circuit wouldn’t work outside of the enclosure? I’ve heard of circuits being quieter inside the metal box, but not that they don’t work at all without one.
