The GHS Contact Core 012-054 Bright Bronze Acoustic Guitar Strings feature a unique design aimed at delivering bright, resonant tones. These strings use an 80/20 copper-zinc alloy, with a contact core that allows better connection between the core wire and the guitar's bridge and soundboard. This design enhances clarity, giving the strings a more defined and piano-like tone, especially in the bass frequencies.

The gauge sizes for this set are .012, .016, .024, .032, .042, and .054, making it ideal for players looking for a balance between light and medium tension, with crisp, brilliant sound qualities​

The contact core design allows the core wire to have better contact with the bridge and soundboard, creating our brightest string. The end result is a richer and more defined bass tone with piano-like clarity.
