Tonal excellence. Combined with unparalleled Japanese build quality. This is what defines the Yanagisawa AWO1S. By building on the success of the legendary A901, Yanagisawa have been able to make an alto sax for those wanting to take music seriously. Made from newly engineered brass, and plated in silver, the AWO1S has an improved sound that’s rife with sonority. And once combined with the re-designed bore and tone holes, you can hear the strong tonal core with flawless intonation. The fresh design of the AWO1S has resulted in new front F keys, right side keys, and right pinky keys – all for your convenience. And for an added touch of luxury, the bell features uniquely styled engraving which has been meticulously done by hand.
