The Sepia Tone Jazz Metal is Gottsu’s standard metal model. Unlike the Master and Double Ring, the Jazz Metal is a completely original Gottsu design crafted from vintage brass and plated with silver.  The Jazz Metal features a moderately bright, fat and outlined (or edged) tone with good projection.

With the 2026 update, the Jazz Metal now features rails that will accomodate the Gottsu sliding ligature (sold separately).

“After making the Sepia Tone VI, an ebonite mouthpiece, I wanted to make a metal model. Because I play Tenor Saxophone, I own vintage metal mouthpieces, so I wanted to make a better mouthpiece than the vintage ones. That was how I started to make Jazz Metal.”
