Vintage Tone ™
The tone of shamisen has changed over the past 50 years, due to the growing aesthetic for tighter and tighter skin. (So tight, traditional wooden clamps are unable to stretch the skin far enough) This has resulted in the shamisen having sharp and almost-metallic tone.
When my partner Nitta-san heard the sound of this specially prepared goat skin, he was filled with nostalgia and excitedly said, “It has a vintage tone!”
