TMH004 Mantic Flex Pedal

The TMH004 Mantic Flex Pedal is an exclusive collaboration between Third Man Hardware and Mantic Pedals, available through the official Third Man Records store. Described as a monophonic synth-fuzz, the Flex has delighted and bewildered listeners since Jack White began using it back in 2014. It stands as one of the more adventurous pieces of hardware to emerge from the Third Man universe — a pedal that doesn't play by the rules of conventional effects processing and invites players to explore genuinely uncharted sonic territory.

Born from a Guitar Solo

The TMH004 was heard prominently on Jack White's guitar solo in "Why Walk a Dog?" — a moment that introduced the pedal's distinct voice to a wide audience and sparked curiosity about the unusual tones White was coaxing from his instrument. That real-world credential, rooted in an actual recorded performance rather than a demonstration reel, gives the Flex an authenticity that few boutique pedals can claim. It wasn't designed for the stage in the abstract — it was already on the stage, doing something remarkable.

A Tonal Landscape Like No Other

The Mantic Flex can provide an array of sounds from thick, phase sweeping squarewaves with pitch divebombs to brutal bitcrushed octaves and fluttery thereminesque squawks. This range is not incidental — it is the point. The Flex is built for players who want to move beyond traditional fuzz and distortion into something more alien and expressive. Whether you're reaching for a synth-like sustain, an unstable oscillating warble, or a hard-edged digital crunch, the Flex rewards experimentation and resists predictability.

An Invitation to Get Lost

Third Man describes the experience of using the Flex as letting loose, getting lost, and finding yourself in the mind-twisting tonal soundscape of the pedal. That framing says something important about the philosophy behind the TMH004. It is not a utility pedal meant to be dialed in and forgotten — it is an instrument unto itself, one that changes the relationship between the player and their sound. For adventurous musicians, that unpredictability is precisely the appeal.

Why Our Gear Experts Appreciate the TMH004

Our gear experts are drawn to the TMH004 because it opens up a dimension of sound that conventional pedals simply can't reach. Its monophonic synth-fuzz engine delivers everything from phase-sweeping squarewaves and pitch divebombs to bitcrushed octaves and fluttery thereminesque squawks — a palette that rewards boldness. With a direct lineage to Jack White's recorded work, it carries real creative credibility. For players who want their rig to surprise them, the Flex is genuinely unlike anything else on the board.
