The Moog Theremini is a theremin known for its intuitive operation and diverse sound palette. I purchased it from Ishibashi Music and have been using it, but I'm selling it to upgrade. There are no operational issues. It includes the main unit, antenna, genuine cable, and manuals. Some of the manuals have stains. It will be wrapped in bubble wrap and shipped in a cardboard box. It has a tuner that allows you to visually understand the pitch, and you can set the scale and root note, making it convenient for sessions and during songs. It also has a built-in delay. This is a convenient and valuable model that doesn't come up for sale often, so take this opportunity. - Model Name: Theremini - Brand: Moog - Included Accessories: Power adapter, registration card, manuals - Control Panel: Dial controls, LCD display - Connection Terminals: Audio output terminal, USB port Thank you for looking.
