Yamaha FC5 Sustain Footswitch  

Fc 4 & Fc 5, these are momentary switches.... there is no polarity at issue here. period. read the owners manual. try to buy a casio if that is what you have! the reversal is in the keyboard itself. Where the on/off switch is!!! Yamaha.... is synonymous with quality. All the pedals are cheap, If I were to break one, (I haven't) I'd go buy another.

It's an ok basic pedal, but not all you'd hope for. I have two of these that I'm not using right now, but still have to go out and buy another pedal because I need one that has the opposite polarity. Some keyboards don't sense the polarity of the pedal, and expect you to use a pedal with specific polarity. So really, would it be so hard to give this pedal a polarity switch like you find on other pedals? Seriously annoying Yamaha.

Overall, this pedal works very good. This is actually the pedal that came with my keyboard, and so far it holds up pretty good. The only problem I have with it is that it slides a lot, which is bad when your performing and need to use the pedal. Other than that it is a well working cheap pedal that gets the job done.

Do not buy this for a Casio or any other standard keyboard that wants a closed circuit for sustain.  Contrary to the suggestions to hold it down while powering it on, Casio doesn't observe that convention for reversing polarity.  To modify this pedal, you will need to physical modify the pedal circuit.

Barebones, but it gets the job done as a sustain footswitch and is inexpensive and sturdy.  As stated in an other review you can change the polarity by holding down the switch before you power on.
