Critter & Guitari Septavox
Note: links to listings are affiliate links for which the site may be compensated.
via this eBay listing
"Critter & Guitari’s rare and revered Septavox in a canary yellow aluminum enclosure is here for your consideration. And yes, those are the signature, C&G wooden buttons
A one-off collaboration between Critter & Guitari and Jack White’s Third Man Records, the Septavox is a portable synthesizer featuring 41 keys, 7 modes, 7 tones, and an internal 3-watt speaker powered by 9v DC center-positive power supply (or four AA batteries for playing on-the-go and jamming in unplugged group settings).
Enjoy MIDI in and out ports, as well as a quarter-inch, monophonic line-out jack for plugging into an amp or mixer/interface.
Conceptually, the Septavox is something like a more accessible, road-ready version of C&G‘s Organelle—designed for plug-and-play use, while rugged enough to be tossed into a backpack without a second thought. Each tone and mode corresponds to a dedicated knob and colored LED indicator. Simply note the color combo of a favorite mode and dial in the volume, tuning, and dual modulation parameters.
The seven modes are: Vibrato, Slide, Two-Octave Arpeggiator, Swell, Octave Cascade, Slicer, Pipe Glide.
And the seven tones: Dirty Sine, Sine, Electric Organ, Square Wave, Sawtooth, Dirty Square, Computer."
