A superb-sounding, versatile and great-value string set, particularly popular with jazz players. 


"Spirocores were the strings I started playing on, and the strings I always return to. I need strings that can cut through in a packed underground punk club or deliver the subtlest of notes in a classical music hall. Emotion and drama at my fingertips, strings that can be brutal and violent one minute, sensitive and quiet the next. Thomastik-Infeld Spirocores have the strength, depth and tone that I rely on day after day."  -- Adrian Stout
