The Spaceman Effects Artemis Modulated Filter is an envelope filter pedal built around blendable High Pass, Band Pass and Low Pass filter controls, each adjustable independently1. Unlike most pedals of this nature, the three filters can be mixed rather than used one at a time, and each of the three filter outputs gives up to +10dB of boost1. That combination of independently adjustable, blendable filters and per-output boost is what sets the Artemis apart from a conventional envelope filter.
The controls
The Artemis departs from most filter pedals in one important way: the High Pass, Band Pass and Low Pass filter controls are each adjustable independently and can be blended, rather than offering a single selectable filter mode1. Each of the three filter outputs gives up to +10dB of boost1.
| Control | What it does |
|---|---|
| Freq | Sweeps the corner frequency of the filter directly, or in conjunction with the internal modulation to set the range of the sweep; keep it turned low for maximum range1 |
| Res | Produces a formant peak ahead of the filter cutoff frequency; at higher settings the additional amplitude of the resonant peak drives the filter into breakup1 |
| Sens | Adjusts how responsive the filter sweep is to the picking dynamics of different instruments; in LFO modes it can dynamically modulate the speed of the LFO1 |
| Amount | Controls the modulation depth in Envelope modes and the speed in LFO modes1 |
| High Pass, Band Pass, Low Pass | Independent, blendable filter controls, each with its own output offering up to +10dB of boost1 |
The 7-mode modulation bus covers both envelope and LFO behavior: you can sweep the filter in both Up and Down directions, and the LFO modes carry 4 waveshapes1. The Exp jack accepts an external expression pedal or 0-5V control voltage through a 1/4" TRS cable, adding foot control over the filter1.
Using it as an EQ
Because the three filter bands are independent and blendable, the Artemis doubles as a tone-shaping tool. The Pedal of the Day reviewer noted that "if you cut the modulation off, they can be used as a sick 3-band EQ"1. With modulation off and up to +10dB of boost available per filter output, the pedal can sit on a board as a filter-based EQ and boost as well as a funk machine.
What reviewers said
Pedal of the Day's review highlighted the Artemis's approach to its filters: "There are controls for High Pass, Band Pass and Low Pass filters, but unlike most pedals of this nature, you don't have " to settle for just one, since the three can be blended1. On the outputs, the review noted that "Each of these outputs gives you up to +10dB of boost"1.
Coverage of the Artemis centered on its filter architecture: blendable High Pass, Band Pass and Low Pass controls, each adjustable independently, with up to +10dB of boost available at each of the three filter outputs1.
The Artemis is a hand-wired pedal from a small builder, so availability can differ from mass-produced pedals. Its Exp jack needs an expression pedal or a 0-5V CV source on a 1/4" TRS cable1.

Questions
Can the Spaceman Artemis be used as an EQ?
Yes. The Artemis has independent High Pass, Band Pass and Low Pass filter controls, and the Pedal of the Day reviewer noted that if you cut the modulation off, they can be used as a 3-band EQ. Each of the three filter outputs also gives up to +10dB of boost, so the pedal can shape and lift different parts of your signal.
Does the Artemis work with an expression pedal?
Yes. The Exp jack works with an external expression pedal, or with 0-5V control voltage sent through a 1/4-inch TRS cable. That lets you sweep the filter by foot or from another device instead of relying only on the internal modulation or your picking dynamics.
Is the Spaceman Artemis true bypass?
Yes. The pedal's switching is true bypass, according to the Pedal of the Day review, which lists the Frequency and Resonance controls alongside a true bypass switch.
What waveshapes does the Artemis offer in its LFO modes?
The Artemis offers 7-mode modulation. Within that, you can sweep the filter in both Up and Down directions, and the LFO modes carry 4 waveshapes. The Amount control sets the speed in LFO modes, while the Sens knob can dynamically modulate the LFO speed.
