Verify before buying

  • What is the cosmetic and functional condition of this specific unit, including any scratchy pots, worn footswitches, or enclosure wear?
  • Which colorway is this unit (Prismatic Cosmos or Slime Green), and is the bypass currently set to true-bypass or buffered, with the selection switch working in both positions?
  • Have all controls been tested, including the three wavefolder voices, all 8 LFO waveforms, and the flow/refractor mode with both sides engaged?
  • Does the external control jack function correctly for both tap-tempo and expression-pedal use, and was it tested with an expression pedal?
  • Does the sale include the original box and any documentation, and what is the total delivered cost to Canada including shipping, duties, and taxes?
