Martin M500 Phosphor Bronze 10-47 12 String
Martin M500 Phosphor Bronze 10-47 12-string EXTRA-LIGHT
Martin Phosphor Bronze Strings are excellent for daily use. Deep, rich bass tones and crisp, ringing trebles. Phosphor Bronze has a slightly warmer sound than bronze.
Martin 92/8 Phosphor Bronze is an alloy comprised of 92% copper and 8% tin with traces of lead, iron, zinc and phosphor. These strings produce a bright but slightly warmer sound than the 80/20 bronze. The phosphor in the alloy helps them retain their new sound for greater consistency.
