I used it as a sub instrument for a very short period, then removed it and kept it as a spare. I don't think I'll be using it, so I'm putting it up for sale. It's the real deal. The sound outputs without any problems. Thank you! Price reduced. 28,000 yen -> 25,000 yen (6/15) 25,000 yen -> 22,500 yen (7/15)
