Native Instruments Traktor Kontrol S4 MK1 Controller with Chroma Caps and power supply.

The channel B gain knob is slightly bent (see last pic) its not bad so I never tried bending it back, you don't really notice it much, other than that its all in great condition.  A few minor scuffs but no damage.  All ins and outs working.

Please make sure your laptop will work with this hardware.  This is legacy hardware and is not supported by current gen Mac OS, I was using it on Windows 10 with Traktor Pro 2 but if you google "Traktor Kontrol mk1 on mac os" you can find information on which mac os is compatible.   Please ask any questions before buying, thank you!
