The Roland KD-7 is an older design kick trigger that dates back to the 90's. It works well and some people really love the feel of it. The downside to it is you need two of these to use a double pedal. So if you are a double pedal player you should look at the KD-9, KD-120, or KD-140-BC. Comes with the special inverted beater that is required to use it and a cable.
