Bought this new but barely used it. See pics for excellent condition. Perfect working order of course. Includes USB cable. Can't find the box though I'm afraid.

The single 3rd Generation Scarlett mic preamp sounds great straight out of the box. Air mode recreates the legendary effect of Focusrite's ISA mic pres and makes vocals and guitars shine. Two balanced outputs are hum-free for pristine monitoring, mixing and mastering with studio monitors.
