Independent shopping perspective
Martin’s MM11 Retro Custom Light set is made for acoustic guitar and uses a SOLID nickel/copper alloy blend. Its reduced pick attack is intended to keep the guitar’s wood character more present, while the resulting voice is mellow with crisp detail. Naturally corrosion-resistant wrap wire adds a practical advantage for a set that is designed to maintain consistent tone. This is the custom-light MM11 option in the Retro range.
