Spaceman Sputnik IIVerified
Based on the Spaceman Effects Sputnik II· 3 other boards clone it
From the post
"Starting with the same germanium transistors as the much-loved original Sputnik, but with slightly different specs, we added a few slight tweaks to get very close to the sonic details of the original circuit. Many of the other parts in the Sputnik II are different but of same or similar value, including many vintage and rare parts.
While extremely similar to the original, the Sputnik II is a beast all its own. The Sputnik II takes everything we loved about the original, and adds in the things we dreamed of after its original release it:
• Full-size control knobs for every parameter • Foot-switchable DRIFT mode, with its own status indicator • Additional FILTER options for maximum tone-shaping • Additional circuitry making it more friendly to active pickups, buffers, synths, pedals, etc
Within Sputnik II lies a plethora of fuzz tones. Smooth, gritty, vintage, modern, thick, thin, buzzy, bassy, splatty, sputtery, noisy, buttery, controlled or very much out-of-control. A truly endless cornucopia of fuzz."
Here is another pedal reverse-engineered by Dino (Digi2t).
He also added an extra diode reverse switch.
For all infos on how to build this pedal you can find Dino's original thread (with his own vero) and schematic on the DIY forum here.

Check before you build · 4 values the reader of this layout was not sure of
- 5n red cap at the top of the board, right of Q3: printed clearly, unusual value
- 499K and 475K resistors: printed clearly, unusual (1% series) values
- 4u7 at the top centre next to D2 is drawn as a red oval like the small ceramics, not as a can; could be tantalum, no type given
- Transistor types BS250 / 3904 / BS170 / BS170 / 2SK30 are assigned from the labels under the board by position; the drawing gives them no designators
