2001: Feature black nylon trebles with silver plated wound basses. The light tension gives you the rasp and snap you want in a flamenco string. Very easy to play they offer superior sensitivity to the touch. These trebles produce a greater aural transparency, and are capable of extraordinary sound projection. The design for the bass strings equals the achievements of the NYLON 202 trebles. The construction improved the ratio of wire exterior wound wrapping to the nylon filament core. This results in a clearer, more sustaining tone. The 2001 series unique string design surpasses all other classical guitar sets with their exceptional memory for pitch and consistent sound production.
