The Mythos 1N34A Mjolnir is a limited edition K-style overdrive pedal from Mythos Mjolnir Overdrive maker Mythos Pedals of Nashville, Tennessee. Released as a Black Friday special in November 2024, it takes the Wildwood Mjolnir platform and loads it with a pair of vintage NOS 1N34A germanium diodes, the diode type at the heart of the original Klon Centaur. MusicRadar reported it as a limited edition clone of Mythos owner Zach Broyles' own Klon Centaur, serial number 16661.
What it is and what it does
The 1N34A Mjolnir is a limited edition version of the Mjolnir, Mythos' K-style drive, built on the platform the company uses for the Wildwood Mjolnir it makes for Wildwood Guitars in Louisville, Colorado12. The "1N34A" in the name refers to the germanium diode type in the clipping stage. Mythos says the 1N34A diodes are part of the formula that makes the original "K" style pedal so special2.
Why germanium matters here: in a Klon-style hard-clipping circuit, the diodes set how hard the signal is compressed as it overdrives. The 1N34A germanium diode has a forward voltage of VF=0.35, quite low compared with the 0.7V of typical silicon diodes, and that lower threshold results in harder compression of the signal3.
Like the original Klon Centaur it is modeled on, the 1N34A Mjolnir uses buffered bypass rather than true bypass, and it has an internal charge pump. It runs on 9V only1. Mythos lists buffered bypass switching on the product page2.
Tweaked against one original
What sets this version apart is what it was tuned against. Zach Broyles tweaked the circuit against his personal Klon Centaur, serial number 1666. In the words MusicRadar quoted from Mythos14:
"I have tweaked this circuit to within an inch of its life to be as close as possible to my personal pedal."
Mythos describes the result this way:
"The amount of gain is the same, voicing, output, it's all there and tweaked in just the right way."
Wildwood roots and the limited edition
The Mjolnir's story starts with Wildwood Guitars. RockBoard's PedalPedia describes the Wildwood Mjolnir as its attempt to make the best "Klone" possible, and after getting a real Klon Centaur the company revised the design to closer emulate the tones of the original4. The Wildwood Mjolnir was updated for 2023, with Mythos going back to the drawing board to get it even closer to Zach's personal Klon Centaur and to improve production4.
The 1N34A Mjolnir is the limited edition offshoot of that work. Mythos offered it in Silver and Gold finishes, with a design reminiscent of its inspiration, and with oxblood knobs to nail the look, as MusicRadar put it12. The Silver version's feature list from the maker includes an internal battery clip2.
The 1N34A Mjolnir is a limited edition and the maker's product page lists it as sold out. Mythos notes that the Wildwood Mjolnir will be restocked soon, so players after this circuit have that route2.

Questions
Is the Mythos 1N34A Mjolnir a Klon clone?
Yes. Mythos describes it as a K-style drive, and MusicRadar reported it as a limited edition clone of Mythos owner Zach Broyles' personal Klon Centaur, serial number 1666. It is built on the Wildwood Mjolnir platform, which Mythos revised in 2023 after examining a real Klon Centaur to get the circuit closer to the original sonically.
Does the Mjolnir use germanium diodes?
The 1N34A Mjolnir uses a pair of vintage NOS 1N34A germanium diodes, the diode type associated with the original Klon Centaur. Mythos says the 1N34A diodes are part of the formula that makes the original K-style pedal special. Germanium's lower forward voltage, about 0.35V against silicon's 0.7V, results in harder compression of the signal.
Is the Mythos 1N34A Mjolnir true bypass?
No. Like the original Klon Centaur it is modeled on, the 1N34A Mjolnir uses buffered bypass switching, and it has an internal charge pump. Mythos lists buffered bypass switching on the product page, and MusicRadar confirmed the same in its report on the release.
Can the Mjolnir run on 18V?
No. MusicRadar states that the 1N34A Mjolnir runs on 9V only, matching the original Klon Centaur's arrangement as replicated in this circuit, which uses an internal charge pump rather than a higher supply voltage.
Is the Mjolnir a limited edition?
The 1N34A Mjolnir is a limited edition version of the Mjolnir, released as a Black Friday special in November 2024. Mythos offered it in Silver and Gold finishes with oxblood knobs, and the maker's product page now lists it as sold out, while pointing players to the Wildwood Mjolnir, which Mythos says will be restocked.
Whose Klon was the Mjolnir modeled on?
Mythos owner Zach Broyles tweaked the circuit against his personal Klon Centaur, serial number 1666. He told MusicRadar: "I have tweaked this circuit to within an inch of its life to be as close as possible to my personal pedal."
