I have for sale a Quad Cortex. The unit is basically mint. I am the original owner but am just outside the return policy so my loss. Never gigged and used only a few times in my studio. The unit has been factory reset and includes all original box, warrant, and equipment (such as power supply). Also including the following:Dunlop volume mini x to be used as an expression pedal Laptop stand for easier use of touchscreen for desktop editing.
