If anyone here plays or plans to play a lot of Alto Flute, and you haven't tried the Yamaha YFL-A421, do youself a favor and get your hands on this thing any way you can. The tone, feel, and response is just like a concert flute. Full bodied, quick response, even in all registers. This instrument is unbelievable. Also, if anyone knows of someone trying to let go of a YFL-A421, please send them my way. Thanks.
