As heard prominently on Jack White’s guitar solo in “Why Walk a Dog?”, this monophonic synth-fuzz has delighted and bewildered listeners since Jack began using it back in 2014. 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.

Mantic Flex (Limited Edition Yellow)

Mantic Flex

Glitched out pitch-mod growls with cerebrum piercing sqwuelches, angry-duck-funk quack, and gargling stutters are all just at the surface of the Flex's sonic potential. With an added Mix control, Filter range selector, and variable speed LFO for tracking modulation, the Mantic Flex Pro shreds expectations like a phone book.

Initially released in 2014, the Mantic Flex continues to set itself apart from other PLL's. The Flex Pro is voiced and biased to offer what we found to be the most usable range of PLL sounds in a broad musical context, without compromising the users ability to experiment.

The Flex Pro comes with an expression jack to control the rate of the LFO.

Der Mantic Hivemind ist eine Nachbildung der FX33 Buzz Box, die den Gitarrensound des Melvins-Gitarristen/Sängers King Buzzo nachzuahmen versuchte. Dieser abstoßende Effekt, einer der wahren Kultklassiker des Designers Jason Lamb, kombiniert eine 2 Oktaven tiefere Rechteckwelle mit einer zischenden Verzerrung und rundet das Ganze mit einem variablen LPF ab.

The Mantic Hivemind is a replica of the FX33 Buzz Box which attempted to emulate the guitar sound of Melvins guitarist/singer King Buzzo. One of designer Jason Lamb's true cult classics, this disgusting effect pairs a fussy 2 octave down square wave with a hissing distortion and rounds out with a variable LPF.
