400, You're welcome...
(ducks and runs)
Generally in Yamaha instruments the 200 series are student, the 400
series is intermeadiate, the 600 series professional, and the 800 series
custom.
From BW and WW catalog. http://www.wwandbw.com/, Yamaha also has a web
page that describes their instruments www.yamaha.com or something like
that.
