Yamaha CG classical guitars (updated series)

Among many other improvements and updates the CG includes a three-piece neck for increased stability against warping and bridgeplate (fitted beneath the guitar’s top) that “has been reduced in size to allow freer vibration of the guitar’s top and a more responsive, open tone together with greater volume.” See more description here. The CG series is considered a professional grade guitar, in contrast to the CGS which is Yamaha’s beginner classicals.
