Expensive pedal, but you get a really high quality for the price. Can control up to two keyboards as a volume pedal, and another one as an expression pedal. Will also work very well as a CV pedal for controlling analog synths or effects that accept a control pedal input (I use it with my Odyssey and/or Moog Minifoogers).
Build is very solid, action is firm but smooth. A little more travel would be welcome, but anyway it is very easy to control fine changes in expression.
The pedal is all metal but not too big and heavy, perfect size and shape. The rubber feet make it stay in place firmly, and the rubberized upper surface gives perfect control (impossible to slip), even if it gets very dirty very easily.
All in all, great pedal!
