This is the YAMAHA electronic drum set "DTX6K3-X". A drum chair and sticks are also included. It works perfectly. I have confirmed the sound output of all pedals and pads. Module operation is also problem-free. It has some signs of use, but is in relatively clean condition. I have cleaned it simply. Free shipping. Set contents: Main unit, hi-hat stand, kick pedal, connection cables, power cable, various manuals, drum key for assembly, drum chair, sticks
