Here’s my third Klon build using the Aion Electronics board. The first one I still have. The second one I built for a friend who plays bass. And this one I built so that I could sell. But, I don’t know, it’s so pretty I might keep it.
The toggle I added isn’t part of the original circuit but it allows me to toggle between the stock capacitor (C7) and another one that allows more bass frequencies to pass through. It’s not a ton of bass, but it’s enough to make a difference.
Here is a gut shot.
