Evah Pirazzi strings provide an intense yet brilliantly focused sound while maintaining a short response and great range of volume. These strings are noted for their stability in both tone and climate changes. Manufactured in Germany, Evah Pirazzi strings are developed from a combination of exclusive new core material and advances in manufacturing techniques. This manufacturing produces combined characteristics of gut and synthetic core strings. Evah Pirazzi strings may stretch more than normal synthetic core strings within the first 2 to 3 minutes of installation and are almost stable within 10 minutes and completely stable after 1 or 2 days. Tests indicate that the best sound results can be obtained when the A-string is used without a fine tuner.
