Hey folks so two things right up front.
1. How the F have I never built and used an audio probe before this?!?!
2. I’m never boxing then rocking ever again
That said I’m thinking this is not as bad as I initially thought. I’ve posted a video where I walk through what the main problem is but I’ll state it here too.
Using the audio probe with all the pedals bypassed the signal sounds fine maybe a tiny bit of noise but nothing I noticed at first. Once I engage any of the effects the ground noise is super bad. Also if I touch the audio probe to ground on the power distribution board I can hear the ground noise and the guitar signal coming through.
I tested the audio probe on a working pedal and when I touch the probe to ground it’s completely silent which is what I expect it should be.
Let me know what you guys think. I’m hesitant to say if there are other issues until I get this issue sorted. If I try to ignore the ground noise the wet signal actually sounds ok.
I realize this is a pretty complex build and I can post pictures or answer any questions on how things are coming in and out of the pedal.
For the power and ground distribution to each board (pedals, bypass boards, two leds, headphone amp) I have power from the dc Jack coming into a solderable breadboard from Adafruit which then goes out to everything effectively creating a common point so nothing is chained off one another it all ties back. For the two Aion pedals, the polarity protection diode and a power filtering cap are off board (it’s on the bypass board) so I used the breadboard to add those in. I’m thinking maybe the caps running to ground are causing the issue.
