Because I believe that this formula is able to offer better tonal qualities than steel can. About 30 years ago an important historical change occurred when synthetic core strings became available. Previously only gut and steel strings were available and there was nothing in between. Because of the benefits that these synthetic strings gave over traditional strings, most violin players made the switch. Gut strings were well-liked, but quite expensive and there were problems with tuning stability. Steel strings were cheap, stable and durable, but their sound quality was not very good. In particular they didn't allow the player to modify and create as wide a range of tones and colours. The majority of cello strings today are still constructed with a steel core.
Synthetic core strings were able to offer the benefits of both steel and gut, and this is why they became so popular. The most important question that I have asked myself for a long time is what stopped cellists accepting synthetic core strings as readily as violinists and violists? Maybe the answer is that synthetic cello strings were never as good as the violin strings? Maybe there just wasn't a definitive synthetic option for cellists available on the market.
When we were asked by our many partners, customers, players and friends to develop cello strings, I started to think about the best formula. It was a real challenge for me. To be honest - it would be have been boring for me to create another steel core cello set since there are many types of steel core strings already on the market. With my many years of experience with all kinds of strings as a violin player, I am convinced that synthetic core strings offer a much better ability to create a beautiful tone than ones with a steel core. What I wanted to do was to provide cellists with a fantastic synthetic core string which gives them tonal colour and power and really enhances the sound of their instrument. This is why we decided to create synthetic core strings for cello.
Switching to synthetic core strings does require a little patience and a few small adjustments in bowing technique. The strings need to be played for a few hours to achieve tuning stability, and for a few days to develop their full sound quality. I am sure that switching to synthetic strings will be worth your while. I think that as more players discover the benefits of synthetic core strings, they will become the preferred option for cellists.
