This is a Teenage Engineering EP-133 K.O. II sampler. It has been used a few times, so there are some scratches as shown in the photos, but it is in good condition as it was used in a smoke-free environment. The product is from a later batch that has been addressed for the initial knob defects, so please rest assured. The included knobs are difficult to remove, so they will be packaged as they are. Please check the product specifications from the official retailer for details on the product. It was purchased from a domestic authorized distributor (Media Integration), so the warranty is also included. It is being offered at a lower price than the retail price, so if you are interested, how about taking this opportunity?
