Thank you for viewing. The center of the 34 strings is the 15th string, which is gut string, so you can feel the difference in tone from nylon strings. This harp is still in usable condition for those who want to start playing the harp. There are minor scratches and signs of use, but there are no problems with the hooks. If you live nearby, I will deliver it. For those who live far away, please consult with me regarding the additional shipping cost.
