The trim, which adjusts the volume when using the microphone, doesn't seem to be working. (I haven't checked the microphone. Please assume it's not usable.) The area circled in red has noticeable scratches. Other than that, everything seems to be fine. Sound output, levels, FX trem, FX ON/OFF, faders, crossfader, scratching, song loading, CUE, TEMPO, 16 hot cues, and loops all worked without issue (I checked them briefly). It's lightweight and very convenient for practicing at home and for outdoor trips. 〇 Pioneer DDJ-400 Only the main unit is included; cables and a PC are not included. Please purchase if you don't mind it being used. I plan to ship it on Saturday. Thank you for looking.
