“[V]ery nice Yamaha MR1 player organ. Everything works. missing one small knob. and we no longer have any of the player cards. But, you can play it yourself…..doesnt need the player cards for that! This is a great instrument that I dont want to store any longer! Comes with bench. Has smoke colored plexi glass hinged top.”
Asking price is $125.00 US. I bet you could haggle it down!
