Yanagisawa S-WO37 Soprano Saxophone (Solid Silver)

A vision in the making since 1894, the SWO37 is the saxophone that will make a statement.

Made from beautiful silver, the SWO37 has an improved sound that’s rife with richness. The re-designed bore and tone holes, you can hear the strong tonal core with flawless intonation. To help with intonation in the upper register, the SWO37 has a dedicated key for top Gs – for your convenience.

The SWO37 even includes a straight and a curved neck for personal preference.To ensure you can play efficiently and effectively, the C# and Bb keys have a rocking table/see-saw mechanism. This mechanism guarantees the easiest transition between these pitches. All of the centre arms on all Yanagisawa saxophones use special pointed pivot screws. These screws precisely maintain the stability of the centre arms and help achieve an exact action.

The SWO37 soprano sax benefits from a newly designed, newly engineered and specially sourced silver material. For added strength across the entire instrument, the keys are mounted to a rib which is then mounted to the body. These sorts of details are essential for professional players, as it means fewer repairs and cheaper servicing costs.
