The Acoustic 13's Bluegrass Heavy strings by Kyser are medium-gauge .013 strings for acoustic guitar. The strings have a phosphor bronze coating that provides a warm, clear, and well-balanced tone. The corrosion-resistant alloy consists of 92% copper and 8% tin-phosphor alloy around a carbon steel core. This results in a durable, tone-stable string with excellent intonation. Just like Kyser's capos, the guitar strings are handmade in the United States.
