I was looking for a high quality sustain pedal for my Yamaha MOXF6. Because I need it for live performance I was looking for a pedal where the cable is long enough. Also it was important that the signal works perfectly with Yamaha keyboards. At first I thought about buying a Roland sustain pedal, but the nice people at Thomann told me that they don't work well with Yamaha keyboards (there are different signals when the pedal is pressed and released. It could be configured in the keyboard user interface, but it was important that it worked out of the box).
In the end I settled for this one. It is a bit heavy but that's a good thing consiedered that it shouldn't move on any floor when playing a live performance.
