Yamaha QY70 Handy Type Sound Module. Body only (batteries not included). Power adapter not included. This is just my personal impression, but I feel it's more compact and has better sound than the QY100. This is a used item, so there are some scratches and marks. The LCD screen display is good. The sponge on the battery box lid has deteriorated (there is some debris inside the box) and has been removed. This does not affect battery operation. I have confirmed the sound by playing demo data on battery power and listening through headphones. All keyboard buttons produce sound. I have also confirmed similar operation with my own adapter (adapter not included). Other operations have not been confirmed. I do not have detailed knowledge of the equipment, so I may not be able to answer questions. Please be aware that this is a used item, so there is some wear and tear. I have checked it roughly, but there may be oversights in the details, so please forgive me. Please purchase only if you understand that this is a used item from a previous era. Please be aware that we cannot respond to claims after arrival. We do not ship overseas.
