ピアノはオーバーホールをすると音色が変わるのか検証してみた。

This is a bonus video from our four-part Yamaha grand piano overhaul project. How did this piano, specially stringed by Manager Kobayashi of our Saku store, transform into a completely original Yamaha model? This time, we'll compare it with the same model. The piano used for the comparison has already been sold.
