This is Rebote 2 from tonePad.com. It sounds great. Very analog. This build was so fun I built.
The design on the box was based on a design I found in a book on Tibetan art.
It was a little work to get everything into a B sized box. But after the solder fumes had cleared there’s actually a little room left over.
Here’s a layout for the Rebote 2 that would fit in a B sized box.
