This is the best expression pedal you can buy.  I had owned one previously, loved it, and unfortunately sold it because I wasn't using it any longer.  Sure enough, I needed one again, and borrowed a few other make/models from friends over the past few months.  None of the others felt solid, and they lacked quality.  One of them, another name brand, didn't even work consistently.  So, I found myself buying the pedal I knew would work and be of high quality.  The Yamaha FC7 is road-worthy, has a great feel, consistency in how it tracks, and will last you for a VERY long time.
