My joystick gave out on my PA600 after 6 months and it only sat on the stand at home and has been very well taken care of. It was repaired and 2 days later it gave out again. I called and am getting a brand new board to replace my old one. But the repair guy told me that the wires had broken at the solder points as they were too tight. Using the joystick put pressure on the solder joints and there you go. It could be that they are using too little or too thin (or both) of wire causing the solder joints to give way. From the threads I have read about Korg joysticks going south, you would think Korg would make a simple adjustment in the wiring avoiding the cost and hassle of a fix.
