KMA Machines’ Mandrake Octo-Shrieker extracts and improves Moai Maea’s Shriek Analog Upper Octave with Fuzz Channel, offered alongside the Queequeg Sub Generator derived from the Maea.
Four controls — Filter (Low Pass), Timbre (±Fuzz Voicing), Dry, Oct+ — shape an analog upper-octave/Octave Fuzz with ultra-fast tracking. Discrete transistor-based fuzz, enhanced rectification topology, and an active pre-gain 2nd-order filter prepare signal for octaval tones; Independent Mix controls balance dry and effected signals.
Compact, top-mounted jacks; true-bypass silent relay-based soft switching; made in Berlin. Power: 9 V DC (centre -, 2.1 mm, >30 mA). As of 2026-07-13, the price was £149.
Obviously the Moai Maea has been back in the news again as the latest one-off Lilac Edition KMA 10 Year Anniversary pedal. Its Sub-Octave Channel was extracted as the stand-alone Queequeg Sub Generator - in two editions, and now it’s the turn of its Analog Upper Octave Shriek Channel with additional Fuzz Voicing.
So this new Mandrake Octo-Shrieker essentially improves on that Channel - with a lot more granularity and shaping possibilities.
Controls - Filter (Low Pass Filter), Timbre (±Fuzz Voicing), Dry (Dry Level), Oct+ (Octave Level).
4 really simple controls here for maximum impact.
This is already a known and well-loved quantity - now simply just extracted and improved as one of the smartest Octave Fuzzes out there - definitely goes down on my wishlist. In many ways I would probably prefer to deploy this + the Queequeg rather than the all-in-one Moai Maea - but perhaps that’s just me!
Such an apt graphic treatment too - just a great concept really well executed - I think these are going to do really well!
Of course available for order on the KMA Machine Webstore and imminently at selected international dealers - where the Mandrake Octo-Shrieker is priced at $169.99 / €169 / £149.
