The Cosmodio Instruments Pet Yeti is an analog distortion and fuzz pedal with a bitcrusher built in. Cosmodio, a Massachusetts-based builder whose principal is one Barton, released it in early 2024 as the company's debut pedal, and it was listed at $21912. It is an original design rather than a clone, combining fuzz, distortion, op-amp fuzz and bitcrushing in one box31.
The maker pitches it as a way to harness a monstrous force: the pedal delivers extreme, unbridled and sometimes unusual distortion, along with the means to scale and sculpt that energy. Its gain range runs from clean boost through crunch, overdrive and fuzz to what the maker calls glitchy madness, helped by a parallel clean path and selectable voicing patterns45.
The controls: Voice, Strength, Shape, Bite and more
The Pet Yeti's front panel carries Level, Tone, Shape and Gain knobs, with Voice and Strength toggles and a Bite control for the bitcrusher31. The two toggles do a lot of the tonal heavy lifting:
| Control | What it does |
|---|---|
| Gain | Sets drive level; combined with the Strength toggle it can produce clean boost, overdrive, distortion and more extreme tones3 |
| Strength | Toggle for headroom; works with Gain to set how hard the circuit is pushed31 |
| Voice | Selects among three voices, each offering a variety of clipping diodes (op-amp, germanium or silicon) and symmetry options31 |
| Shape | Selects which frequencies hit the distortion stage; acts as a pre-tone control at lower gain, with more unpredictable results when other controls are maxed3 |
| Tone | A traditional post-distortion EQ control3 |
| Level | Sets output volume1 |
| Bite | Activates the bit crusher, which transforms the signal into a square wave3 |
The clipping voices are where the Pet Yeti gets its range. Performer Mag's reviewer, Chris Devine, described the options as including asymmetrical hard clipping with a strong midrange presence, and softer symmetrical hard clipping of germanium diodes, selectable via the voicing switch6. Because the voices swap both diode types and clipping symmetry, the pedal works as a sampler for trying different clipping types alongside its bitcrushing flexibility6.
The Bite control is the pedal's signature trick. Delicious Audio's Paolo De Gregorio describes it as activating the bit crusher, which transforms the signal into a square wave, with results ranging from fuzzy to synthy and glitchy or gated3. That puts the Pet Yeti in unusual territory for an analog drive pedal: rather than modeling digital artifacts, it produces them with an analog circuit.
Guitar, bass, synths and drum machines
The Pet Yeti is not guitar-only. RockBoard's PedalPedia says its parallel clean path and tunable wide-spectrum response make it excel at processing not only guitar but also bass, drum machines and synthesizers4.
For bassists specifically, Performer Mag's review noted that Cosmodio had bass players in mind, using the clean blend control to allow an unaffected signal to pass through, balancing clean articulation with drive grit6. On synths and drum machines, the same reviewer found it makes sense as a booster and gain stage that maintains clarity6.
Versions and colors
The Pet Yeti originally shipped in three colorways1:
- Purple Dark Doomy Deathscape
- Neon Nuclear Wasteland (reported sold out as of May 2024)
- Limited Purple Neon Wasteland
Orders are available from the Cosmodio Instruments webstore1.
What reviewers said
The Pet Yeti's debut drew attention as a first release. Guitar Pedal X's Stefan Karlsson called it an impressive first official attempt from Barton, a really cool, highly textured fuzz and distortion, and wrote that he really rather likes the look of the pedal overall1.
"A good pedal with distortion mixed into some fuzz is always a welcome treat here at Pedal of the Day, and we've got a real wicked scorcher for you all today."
Performer Mag's Chris Devine concluded that overall it is a very flexible high gain heavy drive pedal with enough tricks up its sleeve to work in a variety of situations, enough options for drive pedal snobs, and a sampler for trying clipping types and bitcrushing flexibility6. Delicious Audio summed it up as a super-flexible, fully analog fuzzstortion with an added bit crusher circuit, an original design that can offer tones from the classic to the unusual, and from the subtle to the monstrous3.

Questions
Is the Cosmodio Pet Yeti analog?
Yes. The Pet Yeti is a fully analog fuzz and distortion circuit, with an added analog bit crusher section. There is no digital processing in the signal path; the bitcrushing is done in the analog domain, turning the signal into a square wave when engaged.
Does the Pet Yeti work on bass?
Yes. Cosmodio designed the pedal with bassists in mind, and its parallel clean path and tunable wide-spectrum response suit low frequencies. Performer Mag's reviewer found the clean blend control lets an unaffected signal pass through, balancing clean articulation with drive grit.
Can you use the Pet Yeti with synths and drum machines?
Yes. The maker says its parallel clean path and tunable wide-spectrum response make it excel at processing bass, drum machines and synthesizers as well as guitar. Performer Mag's reviewer found it boosts and adds gain on synths and drum machines while maintaining clarity.
What colors does the Pet Yeti come in?
It originally shipped in three colorways: Purple Dark Doomy Deathscape, Neon Nuclear Wasteland, and a Limited Purple Neon Wasteland. The Neon Nuclear Wasteland colorway was reported sold out as of May 2024. Orders are available from the Cosmodio Instruments webstore.
What does the Bite control do on the Pet Yeti?
Bite activates the pedal's bit crusher, which transforms the signal into a square wave. Delicious Audio describes the results as ranging from fuzzy to synthy and glitchy or gated, depending on how the rest of the controls are set.
