The Spaceman Sputnik is a germanium fuzz pedal made by Spaceman Effects, an all-germanium circuit built around vintage Soviet transistors and hand-soldered in Portland, Oregon1. Spaceman describes it as covering an uncommonly wide range of fuzz territory: "Smooth, gritty, vintage, modern, thick, thin, buzzy, bassy, splatty, sputtery, noisy, buttery, controlled or very much out-of-control"1. A Sync/Drift switch gives it a second personality, adding oscillation, synth tones and 8-bit artifacts when engaged.
The original Sputnik first appeared in 2013, and the design has since grown into a family: the deluxe Sputnik II in 2017, the mid-size Sputnik III in 2020, a IIb reissue in 2024, and a silicon-transistor Sputnik I in 202523. The original is listed as sold out on Spaceman's site, as of October 20261.
A germanium fuzz with a wide tonal range
The Sputnik's gain comes from vintage Soviet germanium transistors, the same class of parts Spaceman has used across the family, with the II and IIb adding NOS Soviet-era germanium diodes to the recipe145. Germanium fuzz circuits are known for their character, and Spaceman itself frames the trade-off on the silicon version's page, describing that variant as "Free from the quirks of germanium: noise, temperature sensitivity, and fragility"6. In other words, the original Sputnik keeps those quirks as part of its personality.
Spaceman says the Range control delivers everything from light overdrive tones to thick sustain-laden fuzz, and reviewers have backed up the range claim. Pedal of the Day's 2014 review found the variety remarkable17:
"The amount of different fuzz tones available in this pedal is really astonishing"
The same review described the pedal as "Producing fuzz-tastic sustain and tone for days"7.
The controls: Range, Calibrate, Filter, Sync/Drift and Scan
Three main knobs and two switches shape the sound, and Spaceman stresses that they interact rather than work in isolation1.
| Control | What it does |
|---|---|
| Range | Fuzz gain, from light overdrive to thick, sustain-laden fuzz1 |
| Calibrate | Tone control that interacts with Range for extra versatility1 |
| Filter | Toggle that enables a second tone-circuit variation, roughly doubling the tonal options1 |
| Sync/Drift | Switch that engages the Drift mode: synth tones, oscillation, pseudo-octaves, 8-bit artifacts and more1 |
| Scan | Mini knob that shapes the Drift mode, where all other controls become very interactive1 |
The Drift mode is the pedal's wild card. In Spaceman's words, it "turns the otherwise mild-mannered Sputnik into a corrupt death ray of fuzz"1. Pedal of the Day's review of the Sputnik II described the equivalent mode as "adding in chaotic and corrupted overload fuzz like you've never heard before," noting it was loud, buzzy and hard to control, while the Regular Mode covered "pretty much any fuzz you can think of, with some new original tones thrown in for good measure"8. On the IIb, the Scan control acts as a squelch to tame or unleash that unpredictability5.
Power, input and build
The Sputnik's build centers on a USA-cast aluminum enclosure topped with a durable, engraved vinyl faceplate and a red jewel indicator light, with the tone transferred via quality open-frame jacks1. Spaceman describes the pedal's tonal range broadly, from smooth, gritty, vintage and modern to thick, thin, buzzy, bassy, splatty, sputtery, noisy, buttery, controlled or very much out-of-control1.
Build details from Spaceman include:
- Hand-soldered stacked PCBs and military-spec wiring1
- USA-cast aluminum enclosure with an engraved vinyl faceplate and red jewel indicator light1
- Open-frame jacks for input and output1
- A custom heavy-duty battery connector1
- Everything made and soldered by hand in Portland, Oregon1
Later versions change the switching: the Sputnik I Silicon and IIb use soft-click true-bypass footswitches65, while the Sputnik III moves to true-bypass relay switching with soft-touch footswitches9.
The Sputnik III Cadet, the current machine-made version, has no battery option and requires an external 9V DC center-negative supply10. The II, IIb and I Silicon all specify 9V DC negative center through a 2.1mm jack456.
The Sputnik family: I, II, IIb and III
The Sputnik line has been revised and reissued repeatedly since 2013, and the versions differ in size, circuit and availability21.
| Version | Year | What it is |
|---|---|---|
| Sputnik | 2013 | Original all-germanium fuzz with Soviet transistors21 |
| Sputnik II | 2017 | Deluxe version, same germanium transistors with different specs, limited to 100 units24 |
| Sputnik III | 2020 | Mid-size format, function enhanced over the original and more practical than the II29 |
| Sputnik IIb | 2024 | Reissue and evolution of the Type IIb format, sold on a 48-hour preorder25 |
| Sputnik I Silicon | 2025 | Same circuit layout with NOS silicon transistors, priced at $2991112 |
The Sputnik II added a second mode and further refinements to the original circuit, which Pedal of the Day described as taking "the already brilliant circuit from the original Sputnik Fuzz, and beefs it up even more"8. Its Calibrate knob acts as a wide-ranging tonal control, and its High Filter switch offers three tone options focused on the high and midrange frequencies8.
The Sputnik III inherits and expands on several features of its predecessor, the Sputnik II, and its mid-sized form factor allows for an enhancement in function over the original Sputnik and practicality over the Sputnik II1314. It was offered as a standard edition plus three limited-run designs: Black, Red Moon, and a Soviet-inspired Red13. Ahead of those, Spaceman built a Limited Edition of 3 units loaded with the first-run, fully handmade and hand-wired circuits9. The Sputnik III Cadet incorporates the input transformer from the Sputnik II, which Spaceman says ensures the pedal will behave anywhere in your signal chain, along with features from the original Sputnik10.
The Sputnik IIb was offered in three signed and numbered color options: Black, Gray and White5. The Sputnik IIb Deluxe was likewise offered in three signed and numbered color options, Black, Gray and White, and adds a Low switch with three levels of bass response, set as 3 / 1 / 22.
On the silicon side, Guitar Pedal X's Stefan Karlsson reviewed the Sputnik I Silicon Fuzz in November 2025, finding it "retains the original Germanium Edition's singing, searing tonality" with more volume, gain and range, though without the germanium version's distinctive harmonics overall12. That pedal earned a Silver award in Guitar Pedal X's 2025 fuzz roundup3.

Questions
Is the Spaceman Sputnik true bypass?
Yes. The original Sputnik uses true-bypass switching through what Spaceman calls the heaviest duty mechanical footswitch available. Later versions vary: the Sputnik I Silicon and IIb use soft-click true-bypass footswitches, while the Sputnik III and III Cadet use true-bypass relay switching with soft-touch or momentary footswitches.
What transistors does the Spaceman Sputnik use?
The original Sputnik is an all-germanium fuzz built with vintage Soviet transistors. The Sputnik II and IIb use NOS Soviet-era germanium transistors and diodes, and the Sputnik III Cadet keeps NOS Soviet-era germanium transistors. The Sputnik I Silicon Fuzz instead uses NOS silicon transistors, including 2N3904, 2N4125 and 2N7000 parts plus a JFET.
What does the Sync/Drift switch do on the Sputnik?
In Sync the pedal behaves as a normal fuzz. Set to Drift, it turns what Spaceman calls the otherwise mild-mannered Sputnik into a corrupt fuzz machine, adding synth tones, oscillation, pseudo-octaves and 8-bit artifacts. The Scan mini knob then acts as a squelch control to tame or unleash that unpredictability.
Does the Spaceman Sputnik run on a battery?
The original Sputnik has a custom heavy-duty battery connector, and the Sputnik I Silicon can run on a 9V battery or an external supply. The Sputnik III Cadet has no battery option and requires an external 9V DC center-negative power supply.
Where is the Spaceman Sputnik made?
Every version is built in Portland, Oregon. Spaceman describes the original Sputnik as completely hand-soldered and handmade there, with stacked PCBs and military-spec wiring, and the II, IIb, I Silicon and III are all soldered or wired by hand in the same city.
Is the Spaceman Sputnik still available?
The original Sputnik, Sputnik II, IIb, I Silicon and Sputnik III are all listed as sold out on Spaceman's site as of late 2026. Spaceman has reissued and evolved the design repeatedly, most recently with the machine-made Sputnik III Cadet in the Cadet Series, so new runs appear periodically.
