Kemble Pianos are made by Yamaha. They have been made for about 20 years in a Yamaha factory in England and by the Yamaha factory in Japan. They are equiped with more expensive tone parts to create a warmer and more colorful sound than standard Yamaha pianos.
The vertical pianos have improved soundboards made in Germany and are using a more expensive shaped rib design which allowes the soundboard to vibrate more freely and with more color than similar Yamaha pianos. They also use German Able hammers which allows a warmer and less percussive sound.
The Grand pianos are an imporved Yamaha C2 piano with German Able hammers and a more beautiful case design.
