Thank you for viewing. This is a stereo phaser once sold by Arion. I purchased this model new about 15 years ago, which was used by TK of Ling tosite sigure, and stored it without using it much. It is now discontinued, and this item was stored with the box and instruction manual, so the condition is good and I think it is rare. Also, I checked the sound and confirmed that there seems to be no particular problem. We recommend that you purchase this item with the understanding that it is a used item. Thank you for your consideration. Type...Electric Guitar
