Evah Pirazzi's improved strings are an innovative production technology. The peculiarity of the difference from the usual Evah Pirazzi is the new G string (gold or silver), the E string (stainless steel). These strings have a rich, noble and spacious sound from the lowest to the highest registers, a wide range of sonic shades, and instant response. These strings take a very short time to play. They are completely insensitive to fluctuations in temperature and humidity!
