MASTER 8 JAPAN and K.Yairi, Japan's leading acoustic guitar brand, have teamed up to create the "INFINIX-U ACOUSTIC BLEND," a special pick for acoustic guitars. Based on the MASTER 8 flagship model, "INFINIX-U," this pick features a unique blend of two high-performance resins, INFINIX and ULTEM®. Because acoustic guitars are acoustic instruments that cannot be electrically adjusted, we focused on the purity of sound that emerges the instant the strings are plucked, pursuing a natural, full-bodied tone that's perfect for acoustic guitars. This pick is a special model created for final inspection of guitars at the K.Yairi workshop. Guitars destined for players around the world are checked for sound with this pick before shipping. This is not just a collaboration, but a testament to the trust born from a "relationship in which we share responsibility for sound." Both sides of the pick feature a rubber grip for superior anti-slip properties. The grip pattern is designed to resemble the shape of Gifu, where both brands are based. Craftsmanship and pride in the land are evident in every detail, making this a reliable choice for music without power. Go to the listening page (external site).
