Savarez 500CR New Cristal Corum Classical Guitar Strings, Normal Tension
The Corum strings use the new and improved non-rectified trebles, but the basses are created with a different winding process that seems to extend their longevity and improve their intonation.
The Red Card is the middle tension and the highest tension is called the Blue Card rather than Yellow. The Red basses are warmer than the Blue which are more cutting. Also, there is more of a tone colour difference between the 1st string and the 2nd and 3rd in the Red tension than in the Blue. Otherwise, the two tensions are fairly similar.
Basses: The tone color of these basses is rich and warmer than the Alliance though their projection is still excellent. Their longevity is good, and the intonation is reliable. They allow for plenty of color variety and flexibility for vibrato.
Trebles: These trebles are made out of a new non-rectified nylon, exclusively produced for Savarez, which have a tension perfectly balanced with the Corum basses. They bring nylon strings indisputable improvements in clearness, expressiveness, long lasting, accuracy and ease of playability.
