I was initially unsure whether the keyboard etc. could take damage possibly due to shipping - but it was super well packed to (in a set with stools).
I am of the quality of the article very enthusiastic!
It sounds relatively beautifully clear to other (cheaper) keyboards. The keyboard has its own volume control on the left, you can additionally possible to attach equipment (such as USB flash drive, additional amplifiers, etc.).
Both for home use as well as for example minor roles (parties, weddings, etc.) determined!
Yamaha offers great quality in this sector!
