The Spaceman Atlas III is a medium-gain preamp booster from Spaceman Effects. According to the maker, it stays relatively clean and transparent while adding subtle color and harmonic overtones that grow with gain, and it was specifically created for pushing the front end of tube amps in a rich, warm way, adding sparkle in the highs without muddying the lows1. Spaceman describes the coloration as coming from a discrete preamp design1.
What it does to your sound
Spaceman positions the Atlas III between a clean boost and an overdrive: it is a preamp booster, meaning it adds gain and harmonic content rather than simply lifting volume. The maker's description is that the overtones "become more" pronounced as gain rises, so the pedal can sit near clean at low settings and push into a warmer, colored medium gain at the top of its range2. Players who want more saturation than a straight boost but less than a distortion pedal are the audience Spaceman describes.
Build and enclosure
Spaceman builds the Atlas III into a USA-cast aluminum enclosure with a durable, engraved vinyl faceplate and a vintage dim-able indicator light2. The construction details the maker points to are:
- Immaculate hand-soldered PCB2
- Detailed military-spec wiring2
- Custom Spaceman heavy-duty battery connector2
- Vintage dim-able indicator light2
Finishes and the Red Edition
The standard Atlas III was offered in five finishes, all on the same USA-cast aluminum enclosure with an engraved vinyl faceplate2:
| Finish | Enclosure | Faceplate |
|---|---|---|
| Silver | USA-cast aluminum | Engraved vinyl2 |
| Black | USA-cast aluminum | Engraved vinyl2 |
| Light Blue | USA-cast aluminum | Engraved vinyl2 |
| Copper | USA-cast aluminum | Engraved vinyl2 |
| Chrome | USA-cast aluminum | Engraved vinyl2 |
Alongside those, Spaceman produced a Red Edition: a limited run of only 2 units in a textured red powder-coat with the company's signature black engraved faceplate, a red jewel, and a large solid aluminum control knob. The Red Edition units carry the original fully handmade and hand-wired circuits, and each pedal is signed and numbered inside with a hand-hammered number tag on the enclosure1.
Availability and the Atlas IV
Both the standard Atlas III and the Red Edition are listed as sold out on Spaceman's pages21. Pedal of the Day, reviewing the successor in August 2025, wrote:
"the highly regarded Atlas III: Preamp Booster which has been out of production for several years"
Spaceman's own page for the current model repeats that it "has been out of production for several years"4.
The successor is the Atlas IV MKIV Edition, which Pedal of the Day reviewed on its release in August 2025 as the next generation of the Atlas III3.
If you are shopping for an Atlas III today, you are looking at the used market: the pedal is sold out from the maker and has not been in production for years. The Atlas IV is the current version of the circuit.

Questions
How much did the Spaceman Atlas III cost?
Spaceman Effects' own product pages give two list prices for the Atlas III: $199.00 and $289.00 USD. The two figures appear on different Spaceman pages and the company does not reconcile them, so both are given here as stated. Either way it was priced as a boutique, hand-built preamp booster rather than a mass-produced pedal.
Is the Spaceman Atlas III still available?
No. Spaceman Effects lists the Atlas III as sold out, and Pedal of the Day described it in August 2025 as having been out of production for several years. The Red Edition is likewise listed as sold out. Players looking for the current version of the circuit would be looking at the Atlas IV instead.
What replaced the Spaceman Atlas III?
The Atlas IV: Preamp Booster is the successor. Pedal of the Day reviewed the newly released Atlas IV in August 2025, describing it as the next generation of the Atlas III, which had by then been out of production for several years.
How many Red Edition Atlas III pedals were made?
Two. Spaceman Effects describes the Red Edition as a limited edition run of only 2 units, loaded with the original fully handmade and hand-wired circuits. Each pedal is signed and numbered inside, with a hand-hammered number tag on the enclosure.
What finishes did the Spaceman Atlas III come in?
The standard Atlas III was available in Silver, Black, Light Blue, Copper, and Chrome finishes, each on a USA-cast aluminum enclosure with an engraved vinyl faceplate. On top of those, the Red Edition added a textured red powder-coat with a black engraved faceplate and a red jewel indicator light, limited to 2 units.
