Finally an expression pedal of actual quality! I've tried quite a few expression pedals and I'm usually disappointed by them, but not with the DVP3. First thing to say is that the build quality is superb; built like a tank, and feels very sturdy under foot. The size also really impressed me; it's substantial enough not to feel lost under foot, but not as big as say, the boss, so it doesn't hog space on your board. It's also pretty low profile which is great, as I'd previously had issues closing the lid on my board due to the excessive depth of some other models. The motion is very smooth, no ledges to be found anywhere. Essentially, did everything I wanted of an expression pedal. Works very well as a volume pedal too, obviously!
