Martin MSP4200 Medium Phosphor Bronze Guitar Strings

Martin MSP-4200 Phosphor Bronze Medium Gauge Acoustic Guitar Strings

Martin's SP (Studio/Performance) acoustic guitar stings are specifically engineered for live and studio performances, and where maximum string life is demanded. The SP Series is a high performance guitar string developed through research conducted by Martin with specialty steel producers. Since the development of an ultra-high quality core, Martin SPs resist breakage better than any average string. In addition, the cores of the wound strings and the plain, bare stings are both plated with a smooth, acoustic bronze finish. The golden bronze finish does more than just enhances the looks and feel of the strings, its primary function is to prolong string life, brightness, and enhance the tonal quality to meet the expectations of demanding performers. The 92/8 phosphor bronze wrap wire adds extra warmth to the tone, and takes away a little of the brightness for a mellower overall tone. You can rely on C.F. Martin, for fine acoustic guitars and acoustic guitar strings.
