Hi! Thanks for looking. Please read below, and know that I welcome smart offers from thoughtful enthusiasts.


  • Rare! Discontinued! Only 4 Made by designer/builder Kelby Clark! Stamped with Ouroboros seal.
  • Eurorack compatible!
  • I am the original owner, and it has never left my smoke-free, pet-free home studio environment.
  • Always covered or stored in a container when not in use. 
  • Cherry wood with walnut oil finish.
  • Functionality and condition have not changed since delivered to me in Spring 2020.
  • This unique, handcrafted instrument is sold As-Described.


  • Functions in left-to-right reading order on surface, per manual: 2x LFO, 2x OSC, 3X ATTEN, LPF, RING MOD, HPF, LPG, MULT, LPG, OR LOGIC, MULT, MIXER
  • Great self-generative synth and drone possibilities as standalone. Also great for external processing, musique concrète, interacting with modular gear. Pairs well with Eurorack modules.
  • See the entire official demo playlist on YouTube, and flip through the manual on the Ouroboros website!


  • The instrument itself.
  • A supported power adapter (Truetone 1 Spot).
  • A printed copy of the manual.
  • No warranty, patch cables, or product box (synth never had one). Will package with extreme care.


  • ALLERGY WARNING: The walnut oil finish can be fragrant at close distance, and may cause irritation in sensitive individuals.
  • Totters a bit if the bottom-left corner is pressed, which I believe is from natural wood warping. Only this corner. Has done this since new. Does not occur during normal operation.
  • Glue has spread out beyond feet (which can be nudged). See pictures. Tacky, but does not contact a flat surface.
  • Oscillators (two rightmost knobs in top row) have sometimes had minor tuning instability.
