The YAS and YTS 480 saxophones are a step ahead. A little bit more resistance. An authoritative sound yet a great flexibility due to the separated key guards. Ergonomics, playability and intonation are excellent as you would expect from Yamaha. The new YAS and YTS 480 saxophones feature an improved low B C# connection for better adjustment while the new octave key system from the 62 Series, facilitates the use of custom necks.
