BOSS Dr. Rhythm DR-770 Drum Machine

Description

BOSS Dr. Rhythm DR-770 Drum Machine. Condition is "Used". Shipped with USPS Priority Mail.
This was a friend's dad's who passed away. It was recently found in a closet while moving and given to me to sell for him.
The unit itself is in good shape. A couple scratches on the face and a missing rubber foot pad. Please see pictures.
The power supply was purchased on Amazon a few days ago so it is not OEM but seems to work fine.
Upon powering up I got a low battery message so I replaced the internal 2032 battery with a new Energizer one.
I tested the unit with headphones only and it works fine. I do not have the equipment to test the other audio ports but I have no reason to believe anything does not work. I knew the owner and he took care of his equipment.
If you have any questions please ask.
