This is the Teenage Engineering EP-133 KO II. I purchased it new from a musical instrument store and have only used it a few times at home, so I think it's in very good condition. However, the screen is a part of the product that is prone to scratches, so if you are concerned, you may want to consider purchasing a new one. Please check the images for the condition and included accessories. It became popular and scarce as soon as it was released, and it was difficult to obtain. I pre-ordered it at two musical instrument stores and purchased two units at different times, but I didn't have time to use them, so I'm selling both at the same time. I am selling a large number of samplers, synthesizers, effectors, etc., including Teenage Engineering products, to organize my equipment. [Product Details] Teenage Engineering EP-133 K.O.
