Ringing sound in Arachnid V2 pedal.

[Walter]

Hello,

I just soldered an Arachnid V2 guitar pedal and the effects work great. However, there is a slight ringing sound when I turn the pedal on. I can also hear several pops when turning the pedal on or off.
Does anyone know what could be causing this?

Thanks,
Walter

Does anyone know what could be going on? Should I provide more pictures?

I have one of these and there is no ringing. I would use an audio probe to see if I could narrow down which part of the circuit it is coming from.

Slight pops when turning on or off can be normal for any true bypass pedal. A really loud one would be a different thing
