This is an early Pioneer CDJ. You could call it a long-selling product. The CDJ-100S was seen in quite a few clubs. Pioneer has been supporting the club scene since CDs started entering DJ booths. Pioneer ignited the CDJ boom. Although it doesn't have scratch or loop functions, it does have a "CUE function" that allows you to instantly play from a set point, and despite the price, it's equipped with Pioneer's powerful effects. Also, it has a "master tempo function" that keeps the key the same even if the song's tempo changes, and all at this price. Why not experience the traditional Pioneer CDJ, which has supported the CDJ scene from the very beginning!? CD reading has been confirmed. There is no stickiness on the jog dial. Please judge the condition of the product from the photos. Due to the used nature of the item, no claims or returns are accepted.
