The more observant among you will have noticed that some of these photographs are indeed not the Knight K20. However piano styles are so interchangeable that we don't feel compelled to offer prizes. The Knight K20 was a slightly smaller version of the all conquering K10 but still retained the full eighty eight note keyboard. There are other differences between the two models but they have no material bearing on quality or sound. This instrument has a full tone with a positive touch. Please call for further information.
