I purchased this last December but gave up because it was difficult, so I am selling it. I played it for about 3 minutes and stopped. If you are concerned about the condition, please buy a new one! I think it's in beautiful condition. No returns due to the 3N policy (no returns, no exchanges, no cancellations) to prevent swapping. I am selling at the lowest price, so I will not offer discounts. I will not reply to discount comments. Accessories include a strap, case, and ligature.
