Spaceman Effects Artemis

Portland’s Spaceman Effects just came out with a new filter pedal that will catch the interest of the synthesis and psych-inclined guitarists out there: the Artemis.

Featuring a 2-pole state-variable design, which allows to mix, at once, high-pass, band-pass, and low-pass filters, the Artemis can deliver both envelope or LFO based filter effects. These three filters are controlled through the knobs on the left of the pedal, while the Resonance and Frequency knobs on the right side provide the single frequency push normally found in filter effects.

This approach allows to dial in a variety of tone from the synth-like high-pass filter to the classic wha-style band-pass to more subtle and natural-sounding ones mixing all the frequencies.

The Modulation section consists in a 7-mode LFO that opens up a variety of options to create modulated movement, including 4 wave modes, two envelop modes (upwards and downwards) and a “fixed mode” that bypasses the LFO altogether.

The Sens and Amount buttons control functions that vary depending on the selected mode. In particular, the former controls Dynamic LFO Speed in the four wave modes, while the latter sets the depth of the filter in the Envelope modes and the Speed of it in the wave ones.

The Artemis represents a reimagining of one of the oldest, most prominent families of effects: Filter pedals. Featuring a 2-pole state-variable design with high-pass, band-pass, and low-pass outputs and enhanced modulation and mixing capabilities, the Artemis is a new vector to expand your sonic horizons. A host of animation possibilities from conventional to bizarre await you via the 7-mode modulation bus. From there, Artemis offers the unique ability to access each filter response individually or in tandem, presenting an unparalleled level of custom tone shaping ability. Plug in to an Artemis and explore a distant shore of your creative Sea of Tranquility.


Simultaneous HP, BP, and LP output
Notch filter and custom filter responses possible for phased and vibe-like tones
Up to 10dB of boost per output, with infinite cut
15Hz-5kHz corner frequency range
Modulation may be disabled for use as a 3 band EQ
Additional control via external expression pedal or CV

The Artemis offers envelope sweep of the filter in both up and down directions. Additionally, there are 4 waveshapes in the LFO modes, the speed of which may be modulated using the envelope follower. If that wasn’t enough, the Artemis also boasts expression pedal or 0-5V CV control over the filter. You may also disable the modulation, and use the Artemis as an EQ/tone-shaper.

The FREQ control sets the corner frequency of the filter, the BAND knob controls the center band at that position, the HIGH knob controls frequencies above that, and the LOW knob controls the frequencies below that. With a maximum boost of 10dB, and the ability to cut infinitely, the Artemis has more capability than many dedicated EQs. By having the uncommon capability to mix filter response types, instead of switching between them, the Artemis can be used in a similar fashion to a parametric EQ.

The mixer section allows a wide range of tone shaping options, and filter response types unavailable on traditional pedal filters. For example: notch filtering is available by carefully mixing HP, and LP responses. When notch-filtering is modulated by the LFO, you get a great sounding phaser/vibrato. If your traditional band-pass sound is too thin, or honky, you can beef it up by mixing in a little low-end from the LOW knob. With a variety of classic to experimental sounds, and a versatile array of features the Artemis will be at home in any style of music.

Hand-wired and built in Portland, Oregon, the Artemis features true-bypass relay switching with soft-touch footswitches. On top of the cast-aluminum enclosure sits a durable, engraved vinyl faceplate and jewel indicator light. This pedal is built to last a lifetime, both on Earth or in the vacuum of space.
