Beryl Onyx Series Acoustic Guitar Strings

American Precision. Uncompromising Feel.

The Beryl Onyx Series brings American-engineered precision to your acoustic playing. Built on an American hexagonal steel core and wound with phosphor bronze, these strings deliver a bold, articulate tone with the kind of feel and response that serious players demand. Sitting just below our flagship Diamond Series, the Onyx is the choice for players who want the very best without compromise.
