# Korg Polysix
“Up for sale is my Korg Polysix. Every button, switch, knob, keys, input and output works on this keyboard. I have replaced the original battery about 1 year ago with a rechargeable battery pack as seen in the pictures and also cleaned all the key contacts at the same time. I have the original Polysix cassette, instruction manual and programming manual as well. The lit purple strip you see is EL tape that I added – I think it looks pretty cool but you can easily remove it if you want to. The only reason I’m selling is because I need the money otherwise I’d be keeping it as it can only go up in value! I’ve taken many pictures of it for you and even added a small video to show you that all the program and bank buttons work (these wouldn’t be working if there was a problem with corrosion on the board inside).” Link
