The Thomastik-Infeld Experience For decades, upright bassists have relied on Thomastik-Infeld’s iconic Spirocore strings for their rich sound. Now, electric bassists can experience that same legendary tone with these jazz flatwound guitar strings.

Smooth Playability Crafted with a true ribbon flatwound nickel alloy wrap and a silk inlay, these strings provide a smooth surface that feels incredible under your fingers. Say goodbye to finger noise and enjoy effortless slides and transitions.

Unmatched Clarity A highly pliable steel core enhances the fundamental tone, delivering a rich, warm, and well-balanced sound. Whether you're laying down groovy basslines or driving a mix with punchy low-end, these strings ensure superior definition.

Dynamic Playing Styles Unlike traditional flatwounds, the roundcore design of these strings offers enhanced flexibility, making bends, vibrato, and expressive playing natural. Enjoy consistent tension across all four strings for a balanced feel.

Stands the Test of Time Built with expert craftsmanship, this bass string set maintains their tone, feel, and playability. Whether you're performing on stage or recording in the studio, trust Thomastik-Infeld for long-lasting, reliable performance.
