This IB42 Infinity Bronze from GHS is a single .042 coated acoustic guitar string designed for players who want "coated" longevity but with "uncoated" tone.
Manufactured from 80/20 copper/zinc alloy tightly wrapped around a steel core wire, this string is then coated using a finely regulated MST (Metal Surface Treatment) method. It produces a bright, lively tone with superb longevity.
Should you break a string, this individual .042 can be used as a replacement to complete your Infinity Bronze set, or you can make up a custom set with single strings in any gauges you select.
