Okay will not even try to explain this.
You have a device in front of you.
Just search for the Robot by Death By Audio on Youtube or whatever since the chaotic PCB will let you build a clone of exactly that.
It's just weird.
I think the chip in this was desinged for toy megaphones of whatever.
Don't factcheck me here.
Oh and I included the option to have a extra gain pot because we all want more gain pots I guess.
