The Yamaha Custom Soprano Saxophone Mouthpiece is sculpted out of choice ebonite, a high quality hard rubber which offers a deep resonance and total qualities similar to those of nature wood. Every step of the production, from the initial shaping of the mouthpiece to the final hand crafting of the facing, is done by Yamaha's experienced artisans for complete control ensuring consistent high quality.

Yamaha has spent years working together with many of the world's greatest musicians, studying their mouthpieces and discovering ways to improve them. The Custom series incorporates this experience into the design and manufacture of every mouthpiece in the series. Additionally, the Custom mouthpieces are characterised by a warm rich tone with exceptional clarity; their accurate intonation and comfortable playability have made them popular with many leading artists.
