Bests & Worsts Reviews from Amazon

Ok, I know you just bought this pedal and plugged it in with the power on your Yamaha Digital piano and it works backwards, right? It sustains with the pedal up, right? It has reversed polarity because you didn't unplug your adapter. Just to make sure unplug your pedal, unplug your piano adapter and plug in the pedal and plug in your adapter for the piano and turn on your piano and it should work correctly.
