I am so glad that I discovered these strings, and was able to give them a try. It has been two or three years, so I am going to need new ones for my German-made Andrew Fein cello. These strings are so Great! They have a warm rich sound that is well-balanced, and yet they are quite loud. They are also rather low tension, making them easy to play for my old hands. Someone told me that when installing them, wind the delicate A up to a light tension, and let it sit for a day. The next day, tighten a bit more, and let them sit. On the third day tighten the A up to proper tune. This is easy, and you will be rewarded with a VERY FINE set of strings.
