The AI006 comes out next week and I'm giving one away. If you
There is a raffle here you can enter, I'll be choosing a winner on Monday the 14th. If you can't DIY I'll build it for you (assuming you win) https://aisynthesis.com/product/ai006-eurorack-stomp-box-adapter/
It's a super simple circuit, and the only one I've released where I didn't analyze a ton of competitors, but I assume it's similar to other stomp box adapters, as there's really only one (best practices) way to resist level to 1/20 and then boost it back to x20.
There are other ways to match impedance/levels (there's an article I link to on the above link to talk about those) but this is a circuit I used in my studio to match levels without having to think about it, so I decided to make a commercial version.
