Does anyone have a copy of the old Pyrocumulus build docs? I have the older version of the PCB with the four electrolytic caps in line near the middle of the board and I wasn't sure how it matched up to the current version. Also, is there somewhere on the forum for the older build docs?

Take a picture of the insides and throw it up here. It helps us to know what you're looking at and let's us see if anything has changed between what pedalpcb traced in his unit and what's going on nowadays.

The King of Tone uses different diodes for the hard clipping and soft clipping portions. But in the prince of tone it uses the same four diodes for soft and hard clipping. The switch is implemented differently since it's a front mounted DPDT rather than dip switches inside. If you want to use...

That was a really good episode. It was amusing to me that they seemed to forget that the prince of tone is the high gain version of a king of tone. Yeah it's a bit confusing. The Pauper is set to the high gain mod (which is just changing out R3 for 10k instead of 1k). But it uses the same input...

No. The resistor change is the only requirement for the high gain mod. The pauper was traced from a prince of tone which had a different input capacitor than my king of tone (which had a 22n). Strangely, my king of tone seems to be an outlier with most having a 10n input capacitor. It won't...

From the docs I'd say match the two germanium diodes. D100 is just for power filtering. As for D4-7 it won't matter too much as long as they have a similar forward voltage (boring electrical engineering term and not something you need to worry about). I would just keep those the same like the...

Looks like the electrosmash tubescreamer circuit with shifted filter points (high-pass of ~600Hz, low-pass ~1500Hz). You could easily build this with the little green scream machine pcb and about 5 part substitutions. You'd need a clipping diode switch but those are easy to add externally. Or...

Just opened it up and checked again. Nothing on the other side. Those were the only markings on either of my MCC caps.

Oh man. Maybe my eyes are bad but to me that image has the numbers upside down and reads 751 like the image of the other cap. The glare kind of makes it hard to read but my crappy photography skills are to blame for that.

Here's the other capacitor. Had to take a picture through a magnifying glass because my camera isn't the best closeup.

Mine is the same value in both sides. I'm not gonna pull the caps out just because there isn't enough lead to get them back with my skill and I want to keep it in good condition. It does seem like an oddly high value. I'm wondering if he's changing part values year to year based on availability...

Sure thing. I also confirmed the value with my multimeter. Yeah the diodes are all connected in this alternating pattern underneath which is pretty interesting. I guess in case one fails so the pedal still works?

Ok. I finished tracing my King of Tone and here's what I've found. 1) The High Gain mod is simply changing out the resistor in the feedback loop of the first gain stage that connects to lug 1 of the drive pot. In the low gain it's a 1k and the high gain is 100k. 2) The input cap is 22nF instead...

I can confirm that the drive pot on my high gain side is only 100k. I think there's a resistor attached to it that's 100k on the high gain and 1k on the low gain. I'll know more once I pull the whole thing apart and can properly trace it. I'm very curious to see how well the PoT you traced...

I just finished building my Pauper and noticed something interesting. In the schematic R15 is 100k but in every other schematic for the king/prince of tone that I've seen there's no resistor there. I was wondering if anyone had an idea of why this resistor was added. Maybe it's part of the PoT...

Heck yeah. Like you said, you'll just connect the output of the Scream Machine to the input pad on the Kliche Mini and then wire up the Kliche Mini like the diagram shows. Bear in mind that the ground of each pedal will be the same point. You may experience some noise if you don't do that. A...
