YTP-310 vs YTP-310AD
(Raleigh, NC, 27613)
I bought a digital keyboard YTP 310AD at Amazon.com. The box was received today. It's a YTP 310. There is a sticker on the box saying "It includes an adapter.".
What is the difference between YTP-310 and YTP-310AD? Can we say the box that I received is YTP-310AD?
