had a friend over and we were dinking around with some pedals I grabbed the mystery meat off my board and plugged it into a 9V supply we were using for several others including a cobbler that also uses a charge pump. This is just a single pedal wall wart no daisy chain or anything. Had the worst high pitched squeal (it woke my kid up from his nap lol). Plugged it back into my board power supply at 18v and it works fine. Plugged my cobbler back in to the other one and it works fine. I’m guessing the mystery meat doesn’t like running at 9V, but I thought I had before. Does this make sense ?
