John Pearse Strings were designed with guitarists in mind. British guitarist and folk singer John Pearse co-founded Breezy Ridge Instruments and developed this high-performance line of strings to meet his own and his fellow guitarists' playing demands. We offer a variety of John Pearse guitar strings for 6 and 12 string acoustic, electric, classical and jazz guitars. Also available are banjo strings, mandolin strings and fiddle strings.The John Pearse 80/20 Bronze wound acoustic guitar strings are available in light, medium and new medium gauges. Strings referred to as "80/20" indicate a wrapping made from 80 percent copper and 20 percent zinc. The zinc adds hardness to the string to make it more durable and less prone to breakage. Our Phos Bronze acoustic strings, with 6 different gauges to choose from, feature a bronze and phosphor winding that gives a rich tone with full harmonics. The bronze has a bright quality, and the phosphor is added for protection. The Silk Phos Bronze strings add a silk multifilament to cushion the phosphor bronze winding, providing a more "played in" sound.
