I'm getting quite a bit of noise when turning on my Abyss, and it's likely related to the LFO as the whooshing noise produced is directly affected by the Rate/Intensity/Voice knobs. I was hoping someone could at least confirm if this kind of noise is expected from this circuit. I don't think so as the demos I've heard the sound was pretty clean, but I wanted to ask before I go too far with the debugging.
Attached is a picture of the guts (I just added the shielded wire on the output but it didn't make a difference) and here is a link showing the noise (starts with the pedal off).
I started a separate thread to discuss some potential ground issues as I wanted to eliminate that, but I don't think that's the cause here. I also apologize for all the questions, if it's better to merge them into a single thread please let me know.
