The Juan Hernandez Viviana model is a handmade flamenco guitar, serving as a testament to Alberto Hernandez's artistry and exacting standards. As a signed model, it represents concert-grade sound without the premium price point. Its construction, meticulously overseen by Alberto, captures the essential qualities desired by professional flamenco players: authoritative power, striking projection, a vibrant and luminous tonal character, a distinctive and rapid raspy quality, articulate and robust bass notes, crisp and popping trebles, a strong mid-range, and notably, a low and swift setup.

Juan Hernandez Guitars was established by Juan Hernandez Iranzo. Born in 1948, Juan apprenticed in the Francisco Esteve workshop at the age of 15, eventually becoming a certified guitar maker and ascending to the position of production manager. In 2001, he established his personal workshop under the Esteve banner, crafting his own line of handcrafted classical and flamenco guitars. Following in his father's footsteps, Alberto Hernandez Monfort (born in 1979) began his apprenticeship at Esteve in 1994, swiftly achieving certification and joining his father's workshop. When Juan Hernandez stepped down, Alberto assumed the role of production manager at Esteve and became the head luthier of Juan Hernandez Guitars, personally crafting models that bear his signature.
