The first synthetic-core string is still a top seller for violin and viola players. The sound is brilliant and responsive. However, they can sometimes sound reedy, or even nasal in comparison with other synthetic core strings now available, particularly on new or overly-bright violins. When they are first installed, they have a rather metallic and edgy sound that softens with a few days of playing. The E strings are available in steel or wound, though players often swap to a different. They last well, both physically and tonally. Their small-sized strings are also very popular, for their longevity and softness under the fingers.
(Available for violin, viola and cello, including fractional sizes.)
