I wanted to mention that when I went into the store today, I tried 4 different sustain pedals. All of them worked if you turn off the keyboard, then plug in the new pedal, then turn the keyboard on agin. It doesn't matter if it was negative or positive polarity, the NP-30 changes the pedal to work perfectly.
