From the vendor

Extra Vehicular Activity. Send your tone for a space walk. This is a clone board for the Spaceman Gemini IV. Everything that the Gemini III wishes it could be, but isn't... even if it was.... but not.... errrr.... you know what we mean.

As with the Gemini III, this is germanium and silicon fuzz circuits, running in parallel. This is where the similarities end. There's a much greater degree of fuzz gain and tone control available now, allow you to squeeze out an almost infinite amount of fuzz tones. To infinity... and beyond!
