Octomix

From the vendor

The name kinda gives it away here A (pretty dirty) octave up with to possibility to mix it with your clean signal Pretty damn neat if you ask me But you don't have to ask me After all I am trying to sell these And I am not sure if you can even find videos of this circuit online I could google it right now instead of writing this but I won't I am just counting on your curiousity and your search for tones you haven't heard yet
