PURE BLUES bass strings combine a fat, warm punch with an edge especially designed for the modern bass player. By combining a new and unique Quantum-Nickel with the highest possible standard in winding techniques, PURE BLUES bass strings achieve an unsurpassed sound and feel. PURE BLUES with Quantum-Nickel wrap are brighter, more magnetic and offer more top end clank and accuracy than typical nickel plated strings. Hand-wound on round cores for increased flexibility and more sustain.
