Up for sale is this vintage Yahmaha SHS-10 red FM digital keyboard with MIDI. It comes with its power adapter and shoulder strap. I did test it, and it appears to be in good working condition. I was not able to test all of the functionalities. It can also be powered by 6 AA batteries. I did note some light corrosion in the battery compartment, but it still seems to work without issue. Nice instrument overall. As always, thank you for your interest. Good luck, and happy buying!
