The EarthQuaker Devices Terminal is a fuzz pedal built as a modern take on the vintage JAX fuzz, a pedal better known as the Shin-Ei Companion Fuzz, a Japanese unit prized for its buzzy, aggressive sound and increasingly hard to find on the vintage market1. EarthQuaker Devices describes it as a "Destructive Fuzz Device" and says it uses archaic all-analog circuitry1. The pedal is no longer in production, so it is now a used-market item.
Where the original Companion Fuzz was a bare-bones circuit, the Terminal takes the design three steps further: EarthQuaker added a Voice control and a Treble control, along with greater output volume1. Premier Guitar's launch coverage quoted the maker describing the design as "modeled after my old JAX fuzz. For those not in the know, the JAX fuzz is a re-branded Shin Ei Companion fuzz that is well loved for its buzzy sound," and noted that the Terminal adds control over the gain, fine tuning of the EQ, and a massive adjustable volume boost2.
What the Terminal does
The Terminal is a buzzy fuzz in the Companion Fuzz tradition rather than a smooth, saturated fuzz. MusicRadar's reviewer Trevor Curwen described its range as running from buzzy fuzz "right through to a ripping synth-like Spirit In The Sky tone"5. At lower settings of the fuzz knob, the pedal produces practical drive tones that can be shaped with the tone knobs; keep turning it up and the sound gets progressively more aggressive5.
The pedal is not a dedicated octave fuzz, but it can lean that way. Guitar World's reviewer found that "Delicious Octavia-style octave-fuzz overtones emerge when the treble and fuzz knobs are cranked way up"4.
Controls
| Control | What it does |
|---|---|
| Volume | Controls output volume level as you dial it clockwise1 |
| Fuzz | Sets the gain; lower levels give practical drive tones, higher levels give buzzy fuzz5 |
| Voice | Adjusts midrange focus and overall frequency response; clockwise gives upper mids with an almost nasal, cocked-wah quality, counter-clockwise gives low-mid thickness1 |
| Treble | Tweaks the biting top end6 |
The Voice knob is the heart of the pedal for tone shaping. Guitar World's reviewer called it "where most of the tonal magic lies, particularly in the lower-midrange tones that are produced when the knob is in the range of seven to 10 o'clock"4. The volume control is no afterthought either: the same review noted that "The volume knob can deliver a very generous volume boost, so players don't have to worry about their fuzz tones fading"4.
The enclosure is a flat black box sporting the silhouette of downtown Cleveland's Terminal Tower, topped with Fender-inspired chrome skirted knobs, a nod to the pedal's name and its Ohio origins7.
How it compares to a Shin-Ei FY-2
The whole point of the Terminal is to capture the original Companion Fuzz sound with more flexibility. MusicRadar's verdict on this was direct128:
"Nails the buzzy fuzz of the original. Offers more control than the FY-2."
The trade-off, in the same reviewer's view, is that the pedal has "only one sound"5: it is a buzzy, destructive fuzz rather than a versatile drive platform. Where a vintage FY-2 gives you the buzzy character with minimal adjustment, the Terminal's Voice and Treble knobs let you dial the midrange and top end to fit your rig, and its output level control lets you push the amp harder or match your bypassed volume.
Power and setup
The Terminal runs on a standard 9 volt DC power supply with a 2.1mm negative center barrel, drawing 10 mA1. It is true bypass, so it leaves your clean signal alone when switched off1.
EarthQuaker Devices warns "Do not run at higher voltages!" and recommends pedal-specific transformer-isolated power supplies for its pedals1. Running the Terminal at any voltage above the maker's specified rating is not supported.
The pedal was built one at a time in Akron, Ohio1, and measured 4.75 x 2.50 x 2.25 inches with knobs1, roughly the footprint of a standard single-effect pedal.
What reviewers said
Guitar World's review found the Terminal "plays well with others, from single-coil- to humbucker-equipped guitars and any variety of amps, including Fenders, Marshalls, Voxes and modern-day high-gain boutique amps"4, which addresses a common worry with vintage-style fuzzes: that they only sound right with one particular guitar or amp.
MusicRadar's takeaway was more focused: the pedal nails the original's buzzy character and gives more control than the FY-2, but it delivers only one sound5. For a player chasing that specific Companion Fuzz flavor, that is the point; for a player wanting a fuzz that also cleans up into overdrive, it is a limitation.

Questions
Is the EarthQuaker Terminal still made?
No. EarthQuaker Devices states on its product page that the Terminal is no longer in production. It was released in February 2014 and has since been retired from the lineup, so finding one means looking at the used market.
Can the Terminal get the Spirit in the Sky fuzz tone?
Yes, according to MusicRadar's reviewer Trevor Curwen, who described the pedal's range as running from buzzy fuzz right through to a ripping synth-like Spirit In The Sky tone. Cranking the fuzz and treble controls is what pushes it toward that sound.
Does the Terminal do octave fuzz?
It is not a dedicated octave fuzz, but Guitar World's review noted that Octavia-style octave-fuzz overtones emerge when the treble and fuzz knobs are cranked way up. At lower fuzz settings it produces practical drive tones instead.
How does the Terminal compare to a Shin-Ei FY-2?
The Terminal is modeled on the JAX fuzz, a re-branded Shin-Ei Companion Fuzz. MusicRadar's reviewer found it nails the buzzy fuzz of the original while offering more control than the FY-2, thanks to its added Voice and Treble knobs and greater output volume.
Can I run the Terminal at 18V?
No. EarthQuaker Devices says to run it only at 9 volts DC and warns "Do not run at higher voltages!" The maker also recommends pedal-specific transformer-isolated power supplies rather than daisy chains.
