I am a current DJ and purchased this for home use, but I am selling it because I haven't used it much. I believe there are almost no scratches, discoloration, or signs of use, but please check the images. This is a sale of the main unit only, and I have confirmed that it powers on and is usable. Also, I will transfer the TRAKTOR PRO 3 license after purchase. Please refrain from rating immediately after receiving the item, as there will be communication for the license transfer. Please rate after the license transfer is complete. ------------ The TRAKTOR KONTROL S2 Mk.3 is a 2-deck DJ controller equipped with sampler and loop functions, and is easily usable via USB connection. - Model Name: KONTROL S2 Mk.3 - Brand: TRAKTOR - Connection Type: USB - Control Type: DJ Controller - Functions: Sampler, Loop, Cue - Number of Decks: 2 decks - Number of Buttons: 8 pads - Number of Knobs: 6 knobs 2-channel DJ controller with USB connection and various output ports. - Model Name: Traktor Kontrol S2 - Control Function: 2-channel DJ controller - Connection Ports: USB, Microphone Input, Headphone Output - Brand Logo: NI - Brand Logo: Traktor Please understand that this item has been stored at home and is sold as-is, with no claims or returns.
