Trouble with Cataclysm delay and Cepheid chorus

[Matoni]

Cataclysm Delay - When I breadboarded this pedal, it worked fine; however, now that it is in the box, I get sound when the pedal is in bypass, and I get sound when the pedal is engaged, just not delayed signal. Because I was able to get a delayed signal before I cased it up, I thought it may be a problem with the wiring to the 3PDT switch but when I check I checked to make sure there were no shorts with a multimeter and everything seemed fine. The perplexing thing about this is how it worked before I cased it up but now that it is in the enclosure it doesn't seem to work. I included the gutshot in case it helps to see.


Cepheid Chorus - I haven't boxed this one up yet because I get what sounds like bypassed signal when I put the board on my test rig. I get no chorus sound, only what sounds exactly like the loop I am feeding into the pedal. I have no clue what I did wrong. I used MN3207 and MN3102 chips that I got from a very generous donor (Ryan Z) who mailed the chips to me. Again, I have no idea what I did wrong here and I included the gutshot below of my board.


Thank you in advance for your help. Also I apologize for the messy wiring and bad pictures, I'm just a teenager

do you have plastic on the pots that are under the PCB? make sure nothing is shorting out against them when everything is boxed.

I always cover the back of the pots with 2-3 layers of electrical tape, and I am able to trace the circuit all the way through with no shorts to ground. I also think that if this was the issue, I wouldn't be able to get sound through the pedal when the effect is activated. Thank you for your idea though.

For the Delay pedal, when you say it worked when "breadboarded" do you mean it worked out of the box but not when you put it in the enclosure? That suggests either a short or a bad connection that separated under some alignment pressure when the pedal was boxed.

Have you taken it back out of the box to see it is still works? Might be a good idea to help you isolate the cause.

Electrical tape can be easily pierced by sharp contact points where leads are trimmed. It is easy enough to put something a bit thicker under the pots to make sure there is not a short to the pot case.

Why do you think having a dry audio signal means you do not have any shorts to ground in the circuit? You could have a dry audio path all the way through and still have a short or a bad solder joint in the wet path. Using the schematic and an audio probe will help you isolate the cause if taking it out of the box and insulating the pots don't do it.
