SOLVED (SOLVED) Cepheid Chorus (no sound)

[Discobungle]

Morning!

I’m having a big issue with the Cepheid Chorus I just built. No sound at all. Can anyone see anything in the pics below that might be throwing this off. I will say that Im using a StompBoxParts breakout board but also some bought Love My Switches breakout boards (pedalpcb version on the way). Also attached is the layout of the breakout board I’m using. I wish these were setup universally instead of each company having their own layout

Hard to tell from the pictures, but are you sure you have the correct positive lug connected on the dc jack?

Should be the +9v one, not the battery one:

Do you have sound when the pedal is bypassed?

Yep. Connected correctly.

I’ll also add that I used an audio probe and got sound out of a few resistors. Te LEDs work too. The signal just isn’t getting out.

I think wires 4 and 5 from the breakout board might need to be swapped

nope. No sound at all.

I believe you have the LED and PCB OUT wires in the wrong places, but this wouldn't affect bypass...

Look for any stray wire strands where the wires connect to the breakout board.

That did it. Thanks so much !
