The microtonal revolution has found its new poster child. Following the explosive viral success of the Canadian instrumental duo Angine de Poitrine, Eastwood Guitars has officially launched a production version of the instrument that sparked a thousand Reddit threads: the Microtonal Doubleneck 4/6 Electric Guitar/Bass.
If you’ve been anywhere near a music feed in the last three months, you’ve seen them—two anonymous figures in oversized papier-mâché masks and black-and-white polka-dot bodysuits, playing some of the most rhythmically complex and harmonically “alien” music to ever grace the KEXP studios. Now, that sound is becoming accessible to the masses through Eastwood’s Guitstarter crowdfunding platform.
Who is Angine de Poitrine?
Hailing from the Chicoutimi borough of Saguenay, Quebec, Angine de Poitrine (French for Angina Pectoris) is composed of two “space-time voyagers” known as Khn de Poitrine (guitar/bass) and Klek de Poitrine (drums).
Though they only reached global superstardom in February 2026 after their KEXP session hit millions of views, the duo has been playing together for over 20 years.
Their music—described by the band as “Mantra-Rock Dada Pythago-Cubist”—is a dizzying blend of math rock, Zeuhl, and microtonal experimentation. Their live shows are performance art pieces, utilizing Dadaist absurdity to separate their private identities from their hypnotic, high-energy stage personas.
The band’s rise has been meteoric:
-
2024: Released their debut album, Vol. 1.
-
2025: Won “Artist of the Year” at the GAMIQ awards in Quebec.
-
2026: Their KEXP session (recorded at Trans Musicales in France) went viral, followed by the release of their second album, Vol. II, in April.

The Instrument: Collaboration vs. Tribute
The centerpiece of their sound is Khn’s custom-built, handmade double-neck, originally crafted by Quebec luthier Raphaël Le Breton (Lutherie Le Breton). When Eastwood Guitars saw the surge in interest, they reached out to Le Breton and the band to discuss a signature model.

In a move that aligns with the band’s enigmatic and anti-commercial ethos, Khn de Poitrine declined a direct signature replica. However, the conversation sparked a “full circle” moment for the brand.
“Many years ago, Khn had approached us with a request to build a white, microtonal version of our Eastwood 4/6 Doubleneck,” the company revealed. “At the time, we weren’t able to accommodate the request. Now, thanks to our Guitstarter program, we’re able to bring that vision to life. It’s the Microtonal Doubleneck that could have been!”
The resulting instrument isn’t a 1:1 replica of Khn’s handmade monster, but rather a realization of that original request—a “tribute” that brings microtonal possibilities to a production-line price point.

Is the World Ready for Microtonal?
Microtonal music—which uses intervals smaller than the traditional Western semitone—has long been a niche pursuit. However, with the success of bands like King Gizzard & The Lizard Wizard and now Angine de Poitrine, the demand for “notes between the notes” is at an all-time high.
The Eastwood Microtonal Doubleneck has already smashed its Guitstarter goal, proving that while the polka-dotted masks are optional, the thirst for new sonic frontiers is very real.
MSRP – $1299
