The latest Steinberger masterpiece
Ned Steinberger revolutionized stringed instruments with the introduction of the L2 bass at Summer NAMM in 1979. The L2’s innovative headstock-free design stunned the music world, and prototypes were quickly snapped up by legendary players like John Entwistle of the Who, Tony Levin of King Crimson, and Andy West of Dixie Dregs. Since then, Steinberger basses and guitars have continued to impress musicians and engineers globally. The company's cutting-edge Headless Tuning systems provide unprecedented stability, while the Radius body shape, Fusion necks, and EMG humbucking pickup systems offer an extensive range of tonal possibilities.
