Yamaha QY70 Handy Type Sound Module. Body only (batteries not included). Power adapter not included. This is just my personal opinion, but I feel it's more compact and has better sound than the QY100. Please read the following notes carefully: This is a used item, so there may be some scratches and marks. The LCD screen display is a little faint, but it displays without any problems when the contrast is set to max (see photo). The LCD seems to have a slight discoloration when off, but the display is clear when on. The sponge on the battery box lid has deteriorated (there is some debris inside the box). This does not affect battery operation. The internal battery has been replaced. I have confirmed the sound using the demo data playback with battery power and 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 will be 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 vintage used item. Please note that we cannot accept claims after arrival. We do not ship overseas.
