VERITASâ„¢, we believe is a completely new category of long lasting acoustic strings that last up to 4X longer than ordinary acoustic strings, according to Stefan Grossman, a renowned concert artist, educator, and owner of The Guitar Workshop Catalog. Accurate Core Technologyâ„¢ (ACTâ„¢) is at the heart of VERITASâ„¢ strings. Superior core wire is recognized as the foundation for rich tone, accuracy of intonation, and durability. Accurate Core Technologyâ„¢ was developed to reinforce the core wire and fill in imperfections along the entire length of the core wire. In our opinion, this results in strings with improved pitch retention, and stability. Players tell us VERITASâ„¢ strings sound louder, brighter and last longer. <> Lasts up to 4X longer. - Stefan Grossman <> They make all my guitars sound better. - Carl Verheyen <> I could feel the resonance in my chest. - Ray Adkins <> VERITAS strings last 4X longer than other strings.- Melissa Etheridge <> Long Life <> Extremely stable.
