Thomastik-Infeld Superalloy bass strings deliver modern tone, with balanced spread across the frequency spectrum. They communicate with a full, well rounded bass, throaty mids, and solid treble without brittleness. Since the outer layer of windings is Superalloy, the warm tone is retained. Plus, they are easier on your fretwork than stainless or all steel strings. 34" scale. Gauges: .030 - .045 - .065 - .080 - .105 - .125.
