EP-3 : I used them with Nord Wave 2, Nord lead A1 and Arturia Keylab (I and II)

Good controller, no troubles, easy to adapt as it allows polarity inversion and have a knob to regulate the range.

It is built in plastic, but that is not a trouble because it is quite robust.

The wide movement range and precision allows to make use of it to play organ sounds confortable by using proper volume pedal techniques. As compared with the other alternatives today in the market, If you do not like headaches (polarity, range adjustment, playability) after trying it for a month I suggest to get, or at least to try this one, the quality/price is very good. I have read in some reviews that is very big but for me this is an advantage, even you have more pedals to use.
