The Markbass Balanced Series Strings 4s 45-105 were designed in close collaboration with Italian bass legend Paolo "Pi" Costa to deliver a rich tone for Studio and stage. Thanks to the special studio tuning, in which the outer winding of Nickel Plated Steel is applied to several stainless steel windings, the Bass strings deliver a deep and warm sound with a rich overtone spectrum. In addition, the Markbass Balanced Strings are characterized by a balanced and smooth feel.
