It doesn't seem correct to me based on the schematic but this person's build which is reportedly working has D1 in A-16.

I guess that is simply due to the angle at which the photo was taken, it is actually in B-16 as shown in the layout.  Still looking for other faults in my build.

Hey, man. I checked your layout like you asked and the resistors, cuts, and links placement look ok to me.  https://i.imgur.com/XPYzNzH.gif 


To clear up the previous question, D1 is definitely in B16/D16 https://i.imgur.com/rZdqA4a.jpg


Your caps look ok too but it's a little difficult to see clearly due to the space those greens take up. Do you have a test interface or at least some alligator clips? I'd remove everything from those switches and test by connecting the Distortion Sw 1/6 wire to the guitar cable and Amplitude 2 to your amp cable and see how that goes. You're sure the Clipping Switch, Filter, and Gain pots are good to go?


This is the Rat section, you said your Boost works, triple check this area. https://i.imgur.com/W5MEFjN.jpg  If it looks ok, then we'll focus on the Octave section.






"To backwards, or not to backwards, that is the question"

I looked at the schematic that was used for this layout, at the time, and the anodes are connected to the base of Q4. Even PedalPCB's current schematics are conflicting. They don't have the original version of the schematic anymore since the update but I've got it here. I just inverted the color to make it easier to look at.

Here are a couple of links from their forum where they talk about it. Looks like the first batch of those costly pedals were sent out with the diodes in the wrong way. lol But like the builds I've made from the Dirtbox Layouts page, it still works. I helped a guy on Instagram with his build so there are at least 4 of these floating around out there. I'd call the layout correct, whichever way you want the diodes. https://www.youtube.com/watch?v=om7qM5xzcKE

I did turn mine around and it's the same. I thought it seemed a little less raspy but I dunno, probably just my brain telling my ears it's different because I know it's different. I didn't A/B it. Still jams though. The octave (Green Ringer/Tentacle) isn't really like a "holy $hit!!!" kind of thing. It's just an upper frequency/tonal add-in that gives the overall sound a different color. If that makes any sense.

It's the center switch/blue light on this Hoof Reaper clip. https://youtu.be/yfT5ulgSf5o?t=60

mtk,
I've done as you suggested and added jacks to the wires of Distortion SW 1/6 and Amplitude 2, my signal isn't passing all the ways through.  Here's where I've currently got signal with the audio probe.

I don't know, man. I can't see anything that's out of place, but pictures aren't as good as a circuit in hand. You're 100% that your resistors/caps/etc... are in the correct place and your pots and toggle switch are good and wired properly?

Here's a picture from a build using the current LP layout.
