Mythos Wildwood Mjolnir

The Mythos Wildwood Mjolnir is a low-gain overdrive pedal from Mythos Pedals, built as a replica of a very specific target: the personal silver Klon Centaur owned by Mythos founder Zach. The maker describes it as "our attempt to perfectly replicate Zach's personal silver 'Centaur'"¹, and says the pedal delivers "a beautiful low gain overdrive tone that compresses perfectly and makes your guitar signal just sound bigger"¹.

The Wildwood Mjolnir is a variant of the standard Mythos Mjolnir Overdrive. Mythos says the normal Mjolnir "has a lot of changes from your average 'klone'", while the Wildwood version is the closer sonic copy of the original unit¹. When Guitar.com covered the original Wildwood Edition launch in 2018, it described the pedal as "a modern-day Klon Centaur that you can use as a clean boost or as a smooth, slightly mid-boosted overdrive"².

A low-gain overdrive modeled on a personal Klon Centaur

The Klon Centaur, the original "Horsey-Man" overdrive, is widely regarded as a benchmark low-gain overdrive. Guitar.com's overdrive buying guide calls it "arguably the ultimate low-gain overdrive"⁶, and its circuit has spawned an entire category of replicas, often called "klones". The Wildwood Mjolnir sits squarely in that category, but with a narrower goal than most: rather than copying a generic Centaur, Mythos modeled it on one particular silver unit, Zach's own¹.

Mythos says it "tried our hardest to match the output, voicing, and feel of the pedals it's an homage to", and claims that in blind comparisons the Wildwood Mjolnir is almost impossible to tell apart from the original unit¹. That claim belongs to the maker; what the press added at launch was a practical description of the sound, with Guitar.com noting it works both as a clean boost and as a smooth, slightly mid-boosted overdrive².

The clipping stage uses NOS germanium diodes, specifically NOS D9E diodes¹⁴. Germanium diodes are part of the original Klon recipe, and sourcing new-old-stock germanium parts is a recurring theme across the Mjolnir family, including the limited-edition Mythos 1N34A Mjolnir built with NOS 1N34A germanium diodes⁴.

Power and connections

The Wildwood Mjolnir is mono, with a single input and output⁵. Power is where a player needs to pay attention.

All Mythos pedals operate on standard 9V DC power adapters, center negative only¹. Current draw is approximately 25 mA¹³. If you are nervous about the voltage warning, the pedal also has an internal battery clip and can run on a +9V battery, provided you unplug the input jack when the pedal is not in use¹.

The bypass is buffered, not true bypass¹. Like the original Mjolnir, the Wildwood version retains the buffered output that is part of the Klon-style circuit¹.

The revised design and its changes

The Wildwood Mjolnir has gone through more than one version. The original Wildwood Edition, launched in 2018 in partnership with Wildwood Guitars, was described by Guitar.com as "kinda a reissue of the first Mjolnirs ever made", housed in a larger and more Klon-like enclosure than the original Mjolnir, and promising less noise compared to the original².

In 2023, Mythos went back to the drawing board. After getting a real Klon Centaur in hand and learning from it sonically, the maker revised the Wildwood Mjolnir to get it even closer to Zach's personal unit and to improve production¹³. The specific changes in the 2023 iteration:

• A slight reduction in low mids
• A tuned Treble knob
• Gain and Output taper adjusted to match the feel of the original unit¹

The internal circuit retains the +18V charge pump, the NOS germanium diodes, and the buffered output across the revision¹.

Mythos Pedals says the company worked to match the output, voicing, and feel of the pedals the Wildwood Mjolnir is an homage to, and that in blind comparisons it is almost impossible to tell apart from the original unit¹. The 2023 iteration brings a slight reduction in low mids, a tuned Treble knob, and Gain & Output taper chosen so the pedal matches the original unit's feel¹.

Where it sits in the Mythos lineup

The Wildwood Mjolnir is the Klon-adjacent entry in a broad Mythos overdrive range that also includes the standard Mjolnir Overdrive, the limited 1N34A Mjolnir, and drives built around other classic circuits, such as the Mythos Herculean Deluxe and the Mythos Runestone. For a player weighing a Klon-style pedal, the distinction that matters within the Mjolnir family is fidelity: the standard Mjolnir departs from the average klone with its own changes, while the Wildwood Mjolnir is the maker's closest sonic copy of the original silver Centaur¹.
