I used this as a secondary instrument for a short period, but then removed it and stored it as a spare. I don't seem to be using it, so I'm putting it up for sale. It's genuine. The sound outputs without any problems. Thank you! Price reduced. 28,000 yen → 25,000 yen (June 15th) 25,000 yen → 22,500 yen (July 15th)
