I decided to re-string an old Autoharp, which needed a bit of TLC. I decided on these strings, which I knew that Thomann stocked, and my harp has come back to life. I should have done it sooner ! The tone is rich and full bodied.Great product at a great price, available from a great company. Thoroughly recommended to bring your Autoharp back to its best. Double check though whether you need a A or B style loop or ball ends for your harp.
