Korpa 
b3 model equipped with the Upright "Silent Piano" system (SI Type)
The introduction of the Yamaha b3 to the b series range sees it approach professional standards whilst remaining true to the b series' design philosophy of value and affordability.
The b3 out performs piano's costing a great deal more by incorporating Yamaha's traditional values as well as benefiting from the latest production techniques. b3's powerful yet articulate characteristics are produced by a larger frame and soundboard and higher grade hammers coupled to a proven, high specification action design. For the ambitious performer on a budget, there is no better instrument.
Digital tone
The sounds you get with Yamaha's SI Silent System are especially deep and genuine-sounding, thanks to a tone generator with stereo samplings.
