It's  not the die cast SDX pedal which I have. As it has the older
Simmons logo probably a successor of the die cast pedal? Can you find
out how it works? If it only makes "open", "closing" and "closed" it's
definetely not an SDX pedal, ottherwise if it can make half-open
states also, it should be.
