> So I am trying to adapt guitar pedal circuits which are normally powered by 9V to work at 12V or 24V.
So you want to use a 12V/24V battery/supply instead of a 9V one? All you need is a step-down voltage converter. Depending on if you want to design one or not and your wattage requirements, you could just buy one that already exists from Amazon:

All you need is a regulator. I keep these around. https://www.amazon.com/gp/product/B014Y3OT6Y/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Print off a plastic screw driver and adjust live. These are cheap and solid but that trimmer pot is a little jumpy. Has to be in a case which I have made if you want one.
pot adjustable buck converters, for projects that have a constant power source, they work great.
but like i said i haven't tested them with batteries at all.

Boy oh boy...that was a lot to digest.

I had seen a video or two or more that suggested using the buck converter on the Unify Pro 5V. Another poster had mentioned that the FC should be ample enough to serve as its own buck converter, minimizing any voltage spikes. With my limited knowledge, all I can think is: "well that sounds right." But I surely don't know whether it actually does make sense to implement these additional measures.
I bought a 5 pack of buck converters via amazon a while ago and use them to power LEDs, fans, etc. They're really cheap and greatly expand the range of fans available to use because the output voltage is adjustable.
I like fans from server power supplies. They are extremely reliable and work at elevated temperatures, but tend to be a bit noisy. All the one's I have seen are for 12V operation, so you'll need one of those buck converters.
