Casiotone MT-45 vintage keyboard. Good used condition, tested and works great. Does not include power cord or batteries. It takes 5 D batteries. It also takes a Dc 7.5 V cord or Ac adaptor AD-1. If your search for Ac adaptor AD-1 you will find many cheap adaptors for around $6. This keyboard is missing the Accomp. Volume Control Knob, but you can still turn the metal peg easily with your fingers. All of the keys work great and do not stick at all. The speakers sound great and there is not cracking or static. All of the effects work as they should. This is a very retro, small, portable keyboard that is in great shape for its age (1980's).
