Brass component parts make a vintage sound!

Reproduction of the machine heads with Brass-made string posts and internal washers, which had been used by Gibson® until 1975 and by Fender® until 1966. At present, the string posts and internal washers are made of steel. By changing the material of those component parts from steel to brass, the vibration transmission is greatly improved, resulting in characteristics similar to vintage sound. This series is called “Vintage Tone Revival”.
