Been using this particular model Yamaha volume pedal since the 1980s. This is the same pedal that was included when a Yamaha keyboard (like a DX7 or KX88) was purchased. These days you don't get accessories for "free" when a keyboard is purchased ... but the FC7 is fairly priced and solidly built - so well worth it. I just recently replaced one that I had been heavily using since the mid-1980s ... so they last. The pedal feels good under your foot and it is smooth. If you use more than one, they can be conveniently attached together. The FC7 is one of those rare musical products that hasn't been cheapened over time. I've used it with countless brands of electronic keyboards over the years - so it works with any keyboard that has a pedal input.
