Frequently Asked Questions

• Does this pedal have a gradient on the sensitivity for the sustain, OR is it an on/off sustain switch?
  It appears this is a simple on/off switch pedal. For continuous or gradient performance the phrases to look for in sustain pedal description are “half- damper” or “half-pedaling.” If there is no indication by the manufacturer of one of those descriptions, the pedal is just an on/off switch. If your digital piano or electronic keyboard supports a half-damper, then a half-damper pedal varies the nature of the sustain effect based on how far down you depress the pedal. The only half-damper pedals I have found so are the Yamaha FC3A, Roland DP-10, and Korg DS1H. The half-damper effect emulates the action on an acoustic piano of lifting the felt damping pads only part way off of the strings.

• Does this pedal work with all Korg keyboards?
  The pedal has a reversible polarity, so it will work with all keyboards.

• Is anyone successful getting it to work with a Roland A-800 Pro? I have one and can’t seem to get it to work. Is there more than just plug-n-play?
  It should work. All I can say is try the reverse function (polarity) switch on the pedal.

• Does this go with a Keylab 49?
  The pedal has a polarity switch on the bottom that will allow it to work with almost any keyboard. If when you plug it in the notes sustain without you pressing the pedal do this. Unplug the pedal, switch the polarity switch, plug the pedal in and try again. Sometimes if you press the pedal before you power up the keyboard it will reverse the polarity and function in reverse. Press stops sustain and not pressed sustains. I would say it should work. You can always return it but this is the best universal pedal I have found and it works on my Yamaha, Roland, Kurzweil, and Nord.

• Is this compatible with a Yamaha P105? Debating between this and the Yamaha FC4 pedal. Any feedback appreciated!
  I bought my sustain pedal for Casio WK 7500 76 key. It works great for mine. It has a standard 1/4″ phone jack. That is all I know.

• Does this work well with a Casio piano?
  We have a Casio piano and it works well with it.

• Will this work with a Yamaha dgx-205?
  This pedal is compatible with any keyboard that has a “sustain” or “damper” 1/4″ jack. Those keyboards that do not have such a jack will not be able to use this pedal. It is compatible with either polarity due to a polarity switch on the bottom.

• Is this pedal compatible with a Casio cfx700ppk?
  It’s a standard 1/4″ jack just like old school headphones and everything else. It’s an excellent and durable pedal. Look up yr Casio model and see if its specs fit.

• Does this work with Casio MD 1700?
  The boyfriend’s daughter has an Alesis brand keyboard that was not compatible with Casio MD. We have her on the Dreokee now.

• My pedal now only sustains when on one polarity (despite being depressed/not depressed) and has no effect on the other polarity?
  If switching the polarity switch does not correct your issue….. Some keyboards automatically detect the polarity of a connected pedal and adjust accordingly. Disconnect your pedal, and power off your keyboard. Power back on your keyboard and allow it to fully power up. THEN reconnect the sustain pedal to the keyboard.

• Does this pedal also work for w/ midi boards?
  I am not sure but it is a simple switch pedal, on/off. Probably it will work.

• Is this compatible with the Kawai mp 9500 stage piano, and does it come with a cord?
  The Kawai Mp 9500 comes with a 2-pedal unit (F2r). The SP-2 might work in the jack for the F2r – if it doesn’t, you can plug it into the FSW jack, then program it for sustain. Yes, it has a 6′ cord.

• Will this pedal work with any Yamaha keyboard (digital or electric)?
  This pedal is supposed to be a “universal” pedal that should work on anything with an RCA plug. But you and I both know there are keyboards that some things just won’t work on like they are supposed to. This is such a nice sustain pedal, I would order it, try it out and, if it doesn’t work, return for your money back. I definitely think it’s worth the trouble and I would bet it will work!! Let me know how it works out for you. BTW, mine is plugged into a Casio WK-1630, an oldie but one of the best keyboards I have ever owned and I’ve owned a lot of them, mostly Yamahas. Still have one of the first DX7s sold in this country. Need to sell it but just can’t part with a dear old friend that easily.
