What does an oscillation circuit look like?

In the title. Basically I'm trying to figure out how you add a tweakable oscillation effect to a pedal.

You mean like a feedback looper?

It's basically just a pot that feeds the output signal back into the input. Turning the pot controls how much of the signal is fed back.

I mean kind of like the Hyperion 2 has.

I'm not exactly sure how it works on the Hyperion 2. Maybe we could ask Devi?

But it doesn't seem like it could be too complicated as the description says the only difference from v1 is the Oscillation control. So I'm assuming it's literally just a pot between input and output.

Nice. Thank you.

but if you want feedback in any circuit, just jumper the input to the output.

What does "jumper" mean? I'm a noob.

Put a wire that connects them

That's it? So like

IN ------------------------------- Out
\\------------CIRCUIT-------------//

Yup. Simple feedback loop. Put a pot in there for more noises.

So would I do it like this:

Or this:

And is it just one wire going from the IN and Out? Or are both (terminals? lugs?) used?
