We bought for the Digital Keyboard Yamaha YPT-410, FC-4 pedal, because it is needed for the current pieces of our Juniors. After first trying out he's (FAS) completely happy with it. Plug in and it wakes from sleep instantly. It has a good stop, solidly built and has a very nice sound.
The only drawback: the rubber feet are very small, rather tiny, so the pedal on slippery surfaces, such as parquet, strong slips. Therefore, four instead of five stars.
