Mapex janus GEN II hi-hat double pedal system. What you have here is a rare Mapex Janus gen II double pedal hit-hat combo. I personally bought this new and it’s been sitting in storage and it’s time to sell. I know these are collectible. It still has all the hardware packs, directions, in perfect shape. Some of the pacts of parts have never been open. It has swap out pedal inserts for different playing styles.
