・ Power supply for effects pedals 　YAMAHA AC-320. ・ I purchased it used and have been using it for about 3 years. ・ There are scratches and dirt in various places. ・ A BOSS sticker is affixed to the side. ・ Velcro is attached to the rubber feet on the bottom. ・ Although it is an old item, there have been no problems during use. ・ It has 8 DC9V ports, 　and I think it can still be used for a long time.
