This pedal works really well and will work with both Yamaha and Roland keyboards since you can change the polarity. (Make sure you move the switch before plugging the pedal into the instrument - or you may find it works in reverse).
The pedal comes with a plastic cover to protect the chrome when you are wearing shoes. Don't throw it away thinking its part of the packaging like I did.
Worth noting that the the first pedal I got clicked noisily when you pushed the pedal down - probably needed some grease. However Anderton's replaced it for another which works perfectly. Suggest you try it out before leaving the shop - but guess mine was an exception since this pedal has excellent reviews everywhere.
