Introducing the Yamaha b3 TC3 TransAcoustic upright piano
The b3 is the range topping model in the b Series, and while assembled in Yamaha's Indonesian factory it in fact shares many components with the Japanese built model U1. The design is based on that of the U1, including a solid spruce soundboard and 5 back-posts but with an emphasis on balancing performance and value for money.
First and foremost an acoustic piano, a TransAcoustic piano is a versatile tool which combines the best features of a digital piano with the inimitable resonance and feel of an acoustic instrument.
Specially positioned transducers transform the piano's soundboard into a natural loudspeaker, meaning you can practice at a lower volume without wearing headphones. Dominic Barnett – Chamberlain Pianos
