The Mythos Pedals Argo is an Octave Up Fuzz, a pedal that produces the classic octave-up fuzz sound heard on familiar records. Mythos describes it as inspired by the now legendary "COB" fuzz box, pushed in a slightly more aggressive direction, giving you what the maker calls "a very angry fuzz sound when you need it but also opens up the flexibility of the unit."1
Controls and modes
The Argo's front panel carries a Volume control, which adjusts the output.1
What sets it apart from the vintage octave fuzzes it draws on is a blend control. Mythos points out that it "has one feature those vintage units never had, a blend control," letting you dial in how much octave fuzz sits on top of your base tone.1
Mythos publishes three recommended settings, each aimed at a different use:
| Setting | What it does |
|---|---|
| Hidden Octave | Blend in some Octave Fuzz with your favorite drive1 |
| Upper Limited | Removed the Fuzz for just Octave1 |
| Experienced, Are You? | Classic Octavia Sound1 |
The Upper Limited setting runs the Argo as an octave effect with the fuzz removed, so it can serve as an octave-only pedal as well as a fuzz.
On the board
The Argo uses mono in and out jacks, and like all other Mythos Pedals the maker uses high quality panel mount In, Out and DC jacks.1 Its current draw of approximately 10 mA is light by pedal standards, so it fits easily on a shared power supply output.1 The enclosure measures 4.82" L x 2.62" W x 1.43" H, a compact footprint for a pedalboard.1
If the Argo interests you, it sits within a wider Mythos fuzz range that includes the AU-79 Fuzz, the 1347 Silicon Fuzz, the Positron Collider and the Big Puft. For more on the effect type itself, see Fuzz Pedals and Octave & Pitch Pedals.

Questions
How much current does the Mythos Argo draw?
Mythos Pedals lists the Argo's current draw as approximately 10 mA, which is light enough for any standard 9V pedalboard power supply.
Does the Mythos Argo have a blend control?
Yes. Mythos Pedals says the Argo has one feature those vintage units never had, a blend control, so you can mix the octave fuzz in with your clean or driven tone rather than committing to the full effect.
How big is the Mythos Argo?
The enclosure measures 4.82 inches long by 2.62 inches wide by 1.43 inches high, so it sits comfortably on a crowded pedalboard.
Can the Argo be used for octave without fuzz?
Yes. Among Mythos's recommended settings is one called Upper Limited, described as having removed the fuzz for just octave, so the pedal can run as an octave-only effect.
