Parentheses OCT_1-3 mislabeled?

[grawlinson]

Quick question, I’m checking out the Parentheses and the schematic has me a bit confused.

The OCT_1-3 connectors that go out to the 3PDT footswitch don’t make sense to me. Namely, the labeling. Shouldn’t 2/3 be swapped?

They're just sequentially numbered pads, the numbers don't correspond to pot or switch lugs or anything like that.

Technically though, yes, if the pads were meant to represent a toggle switch pads 2 and 3 would be swapped. (Pad 3 is the "common" lug)

It might make more sense if you see that the pads across the bottom aren't in sequential order:

Man. I just lost 15 minutes following traces on the wiring PCB, scratching my head, before I realized that's not the actual PCB and the RefDes on that image is wrong as well.

Phew, I’m glad that was cleared up. Thanks for the speedy reply & explanation!

Don't feel bad, it took me a few minutes to make sense of it too, and it's my mess.

The build doc for this one is an older one in Adobe InDesign format... I'll have to recreate it with Affinity Publisher before I can make any modifications but when I do I'll renumber those pads and possibly redraw it in a dotted rectangle so they are properly represented as a switch.

Semi-related, what are some silicon diodes I can use to replace the germanium ones with?

My other RAT pedals have BAT41+14ohm resistor in the hard clipping sections, but I don't know what would work well in the octave part of the circuit.

Use 1n5817s. Matched for octave section.
