Spark Control X control pedal for Positive Grid. I am selling it because it doesn't seem to work the way I expected. I have only used it indoors once or twice, so it's still in great condition and you can use it for a long time. All accessories are included. Please note that the instruction manual is in Chinese as I purchased it from a Chinese website.
