《Includes a transfer ID for Traktor Pro 4 as a bonus》 Native Instruments TRAKTOR KONTROL Z1 TRAKTOR KONTROL X1 MK2 (Also includes a power adapter for TRAKTOR KONTROL Z1.) This is a set. The knobs have been customized to green. Operation has been confirmed. ※ Includes one DJ USB cable and two dedicated cases as a bonus. Please only purchase if you have some existing knowledge. Everything in the pictures is included. Please confirm all functions immediately upon arrival. I have taken good care of them, but they have been used for several years, so there is some wear and tear, but they are relatively clean. Negotiations for price reduction are welcome, but the first person to purchase gets priority, even during negotiations. This is a used item, so it is what it is. Not recommended for those who are overly concerned about condition. ※ To prevent trouble, I will not reserve the item for a specific buyer.
