The Spaceman Equinox is a limited edition multi-band, semi-parametric EQ pedal from Spaceman Effects, hand-wired and built in Portland, Oregon1. Spaceman describes it as "an expansive tone shaping tool inspired by studio equalizers of the past," a studio quality EQ made explicitly for instrument level signals rather than a line-level rack unit squeezed into a box1. Delicious Audio, reporting the launch in August 2022, called it "a hand-built multi-band, semi-parametric EQ with tons of headroom"2.
The pedal is now sold out at its maker, and it was built in small numbers, so this page is a reference for what the Equinox is and how it works rather than a buying guide12.
A Pultec-inspired circuit
The Equinox's circuit is a reinterpretation of the Pultec EQP-1A, the classic vacuum tube studio equalizer. As Delicious Audio put it when the pedal launched: "The Equinox is not an exact replica of the unit, but a reinterpretation of it, optimized for electric guitar"2. The core is a passive circuit adapted from the studio equalizer, with new input and output stages built around it to suit a pedalboard2.
The Pultec lineage shows up in the band structure. The EQP-1A is known for its separate cut and boost controls on overlapping frequencies, and the Equinox follows the same idea with "dedicated Cut and Boost bands with interleaving center frequencies"2. Delicious Audio described the result as "carefully crafted gain staging and highly interactive frequency bands with interdependent cut and boost sections, custom tuned for tons of vintage vibe"2.
Spaceman is not the only maker working this seam: Origin Effects' M-EQ DRIVER also takes its high-frequency EQ circuit from the Pultec EQP-1A, showing how that studio design keeps resurfacing in pedal form3.
The controls: low, high cut and high boost bands
The Equinox is divided into three sections1:
| Section | What it does | Filter order |
|---|---|---|
| LO band | Boost and cut of low frequencies | First order1 |
| HI CUT band | Cuts high frequencies | First order1 |
| HI BOOST band | Boosts high frequencies | Second order1 |
The HI Boost and HI Cut sections each have a separate rotary knob selecting the center frequency, and those frequencies are optimized for guitar rather than copied from the studio unit2. The filter order matters for how each band behaves: the second order HI BOOST band has a steeper curve than the gentler first order LO and HI CUT bands1.
Delicious Audio's EQ pedal buying guide also highlights a Tilt-style behavior, noting that "the filter curve is variable, moving from lo-pass to band-pass to high-pass by turning the Tilt knob"4. That gives the Equinox a broader sweep than a fixed-curve EQ, from a dark low-pass shape through a mid-focused band-pass to a thin high-pass.
Expression control
The Equinox includes an Expression In jack. In Delicious Audio's buying guide, Griffin Jennings explains the appeal: "while an Expression In will let you plug in an external rocking pedal for some old-school wah fun"4. Plugging in an expression pedal lets you sweep the EQ with your foot, turning a static tone shaper into something closer to a filter effect.
Power and switching
The Equinox draws 2mA in bypass and 4mA engaged1. That is a very light current draw, so it places little demand on a power supply, and the maker's listed specifications include no battery option1. Spaceman describes the pedal as offering "massive headroom"1, and the low engaged draw means it can sit on a shared supply without straining the total budget.
The Equinox draws 2mA in bypass and 4mA engaged1. The maker's listed specifications include no battery option, so plan on a pedalboard power supply1.
Current draw is low for what it does: 2mA in bypass and 4mA engaged1. Switching is mechanical true bypass with a heavy-duty latching footswitch, so the pedal is fully out of the signal path when off1.
Build and the Comet Edition
The Equinox sits in a cast-aluminum enclosure with a durable, engraved vinyl faceplate and a jewel indicator light on top1. Spaceman hand-wires and builds each unit in Portland, Oregon1.
The Comet Edition Equinox is the limited run: 222 units, each with a hand hammered nameplate and signed documentation1. With the pedal listed as sold out by its maker, the secondhand market is where remaining units change hands.

Questions
Is the Spaceman Equinox true bypass?
Yes. The Equinox uses mechanical true-bypass switching with a heavy-duty latching footswitch, so with the pedal off your signal passes through without active buffering. Spaceman Effects lists this on the product page, and Delicious Audio reported the same when the pedal launched in 2022.
How many Comet Edition Equinox pedals were made?
The Comet Edition Equinox is limited to 222 units. Each one carries a hand hammered nameplate and comes with signed documentation. Spaceman Effects built them all in Portland, Oregon, and the edition is now sold out at the maker's listed price of $399.00.
Does the Spaceman Equinox have an expression input?
Yes. Delicious Audio's EQ pedal buying guide notes that the Equinox has an Expression In jack, so you can plug in an external rocking pedal for what the guide calls some old-school wah fun. This lets you sweep the EQ hands-free rather than working the knobs.
Is the Spaceman Equinox still in production?
No. The Equinox was a limited edition release, and Spaceman Effects lists it as sold out. The Comet Edition ran to 222 units, hand-wired and built in Portland, Oregon, so finding one now means looking at the secondhand market.
