Thank you for viewing. This is a Super Chromonica 270 in the key of C. I purchased it new several years ago and only used it 2-3 times before putting it away, so I am now offering it for sale. I am a harmonica novice, so please understand that I may be limited in my ability to answer questions. All the notes sound, but I cannot judge whether they are correct. Therefore, I ask that only those who can perform maintenance, and who understand that this is a used item, and have knowledge of such, purchase it. No claims and no returns, please. The items for sale are the case and the harmonica itself.
