LA BELLA’S SILVER-PLATED SETS ARE MADE WITH SILVER-PLATED COPPER WIRE, HAND-WOUND ON A STEEL CORE. FIRST INTRODUCED BY LA BELLA IN THE 1940S, THIS TRADITIONAL STYLE OF STRING HAS SLIGHTLY LESS TENSION THAN BRONZE OR BRASS WOUND STRINGS. AS A RESULT, OUR SILVER-PLATED STRINGS PRODUCE A UNIQUELY CLEAN AND CRISP TONE.
